a) The relevant population is the heavy soft-drink users in the given case, and the appropriate sampling design that should be used is  stratified random sampling. The list of all heavy soft-drink users is the sampling frame.

b) Cluster sampling refers to a sampling design where population is divided into naturally occurring groups and a random sample of clusters is chosen.

The advantages are efficient, easy to perform, and used when the population is widely dispersed. The disadvantages are sampling errors, have lower level of precision, and have the standard error of the estimate.

a) The relevant population for the public relations research department to investigate the initial reactions of heavy soft-drink users to a new all-natural soft drink is heavy soft-drink users. The appropriate sampling design that can be used to investigate the issues is stratified random sampling.

Stratified random sampling is a technique of sampling in which the entire population is divided into subgroups (or strata) based on a particular characteristic that the population shares. Then, simple random sampling is done from each stratum. Stratified random sampling is appropriate because it ensures that every member of the population has an equal chance of being selected.

Moreover, it ensures that every subgroup of the population is adequately represented, and reliable estimates can be made concerning the entire population. The list of all heavy soft-drink users can be the sampling frame.

b) Cluster sampling is a type of sampling design in which the population is divided into naturally occurring groups or clusters, and a random sample of clusters is chosen. The elements within each chosen cluster are then sampled.

The advantages of cluster sampling are:

The disadvantages of cluster sampling are:

A situation where cluster sampling would be appropriate is in investigating the effects of a new medication on various groups of people. In this case, the population can be divided into different clinics, and a random sample of clinics can be selected. Then, all patients who meet the inclusion criteria from the selected clinics can be recruited for the study. This way, the study will be less expensive, and it will ensure that the sample is representative of the entire population.

An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. This constant difference is called the common difference.

The sequence can be represented as {a, a + d, a + 2d, a + 3d, ...}, where 'a' is the first term and 'd' is the common difference.

The partial sum of an arithmetic sequence refers to the sum of a portion of the sequence, starting from the first term up to a given term. The formula for the partial sum of an arithmetic sequence is Sn = (n/2)(2a + (n - 1)d), where 'Sn' is the sum of the first 'n' terms, 'a' is the first term, 'd' is the common difference, and 'n' is the number of terms being summed.

The formula for the sum of the first 'n' natural numbers, also known as the Gaussian formula or the sum formula for an arithmetic series, is Sn = (n/2)(a + l), where 'Sn' is the sum of the first 'n' natural numbers, 'a' is the first term (which is 1 in this case), 'l' is the last term (which is 'n' in this case), and 'n' is the number of terms being summed.

To calculate the sum of all thirty-six numbers on the roulette wheel, we can use the sum formula for the first 'n' natural numbers. In this case, 'n' is 36. Thus, the sum is given by S36 = (36/2)(1 + 36) = 666.

Now, let's consider the arithmetic sequence given. The sixth member is 45, and the eleventh member is 80. We can use this information to find the first term and the common difference.

Using the formula for the nth term of an arithmetic sequence, we can set up two equations:

a + 5d = 45 (since the sixth term is a + 5d)

a + 10d = 80 (since the eleventh term is a + 10d)

By solving these equations simultaneously, we can find the values of 'a' and 'd'. Once we know the first term and the common difference, we can determine the twenty-first term by using the formula a + 20d.

Answer:

quite simple

Step-by-step explanation:

When multiplying a monomial by a monomial, multiply the coefficients and then multiply the variables. When multiplying variables that are the same, use the product of powers property to add the exponents. When multiplying a monomial by a binomial, multiply the factors of the monomial into each term of the binomial.

Answer:

y=0.5x-4 or y=\(\frac{1}{2}\)x-4

Step-by-step explanation:

For this equation, it is mostly just rearranging variables.

We start with 3x-6y=24.

By subtracting 3x from both sides, you get -6y=-3x+24.

From there, dividing both sides by -6 leaves you with y=0.5x-4 aka y=\(\frac{1}{2}\)x-4 depending what format is asked.

Given the probabilities P(A) = 0.7, P(Ac) = 0.3, P(B|A) = 0.4, and P(B|Ac) = 0.8, the joint probabilities can be calculated as follows: P(A and B) = 0.28, P(A and Bc) = 0.42, P(Ac and B) = 0.12, and P(Ac and Bc) = 0.18.

The joint probability P(A and B) represents the probability of events A and B occurring simultaneously. It can be calculated using the formula P(A and B) = P(A) * P(B|A). Given that P(A) = 0.7 and P(B|A) = 0.4, we can multiply these probabilities to obtain P(A and B) = 0.7 * 0.4 = 0.28.

It can be calculated as P(A and Bc) = P(A) * P(Bc|A). Since the complement of event B is denoted as Bc, and P(Bc|A) = 1 - P(B|A), we can calculate P(A and Bc) as P(A) * (1 - P(B|A)) = 0.7 * (1 - 0.4) = 0.42.

Finally, P(Ac and Bc) represents the probability of both event A and event B not occurring. It can be calculated as P(Ac and Bc) = P(Ac) * P(Bc|Ac). Using P(Ac) = 0.3 and P(Bc|Ac) = 1 - P(B|Ac), we can calculate P(Ac and Bc) as P(Ac) * (1 - P(B|Ac)) = 0.3 * (1 - 0.8) = 0.18.

Therefore, the joint probabilities are: P(A and B) = 0.28, P(A and Bc) = 0.42, P(Ac and B) = 0.24, and P(Ac and Bc) = 0.18.

The best estimate of the remaining life of Lourdes Corporation's bonds is 14.82 years.

Lourdes Corporation would have to set a coupon rate of 10.07% to issue new bonds at par.

To find the remaining life of the bond, we need to use the formula:

Remaining Life = (ln(Par Value/Market Price)) / (2 * ln(1 + Coupon Rate/2))

Substituting the given values, we get:

Remaining Life = (ln(1000/1327.36)) / (2 * ln(1 + 0.13/2)) = 14.82 years

B. To find the required coupon rate for new bonds, we can use the formula:

Coupon Rate = (ln(Par Value/Call Price) + Yield Rate) / (2 * ln(1 + Call Price/Market Price))

Substituting the given values, we get:

Yield Rate = 0.13 (given)

Coupon Rate = (ln(1000/1075) + 0.13) / (2 * ln(1 + 1075/1327.36)) = 0.1007 or 10.07%.

The mean price per item can be calculated by dividing the total amount spent ($68.80) by the number of items purchased (15). Therefore, the mean price per item is $4.59.

To find the mean price per item, we divide the total amount spent by the number of items purchased. In this case, the total amount spent is $68.80 and the number of items purchased is 15.

Mean price per item = Total amount spent / Number of items

Substituting the given values:

Mean price per item = $68.80 / 15

                 = $4.59

Therefore, the mean price per item is $4.59. This means that, on average, each item costs approximately $4.59 based on the total amount spent and the number of items purchased. The mean price per item gives us an idea of the average cost of each individual item in the purchase.

Answer:

Let, the c.p be x.

Given,

profit % = 20%

S.P = rs 816

c.p = x

We know,

profit = p% of c.p

         = \(\frac{20}{100}\) * x

         = \(\frac{x}{5}\)

now,

   C.p = profit + s.p.

        x = \(\frac{x}{5}\) + 816

        x = \(\frac{x+ 4080}{5}\)

       5x = x + 4080

       5x-x = 4080

       4x = 4080

         x = \(\frac{4080}{4}\)

In the given regression model, Yi = 30 + B1Xi + B2Di + B3(Xi x Di) + ui, B3 represents the interaction term between the continuous variable Xi and the binary variable Di.

The coefficient B3 indicates the difference in the slopes of the two regressions when Di = 0 and Di = 1.

Thus, it shows how the effect of Xi on Yi changes depending on the value of Di.

C) indicates the difference in the slopes of the two regressions.

In the given regression model, ß3 is the coefficient of the interaction term between X and D, which is (Xi x Di). The interaction term shows how the effect of X on Y changes when D changes from 0 to 1.

Therefore, the coefficient ß3 indicates the difference in the slopes of the two regressions (when D = 0 and D = 1), which represents the effect of the interaction between X and D on Y.

Option A is incorrect because the slope of the regression when D=1 is given by the coefficient ß1 (the coefficient of X), not by ß3.

Option B is incorrect because the standard error of the coefficient ß3 can be normally distributed in large samples, even if D is not normally distributed.

Option D is incorrect because the product (Xi x Di) is zero when Di = 0, but ß3 can still have a non-zero value when Di = 0.

C) indicates the difference in the slopes of the two regressions.

Since T(n) does not have a closed form solution, we cannot determine whether T(n) = O(g(n)) without further information or analysis. Therefore, we cannot provide a conclusion about T(n) = O(g(n)) in this case.

To solve the given recurrence relation T(n) = 2T(n - 1) - T(n - 2) + 2, we will first find the characteristic equation.

Assuming T(n) = xⁿ, substituting it into the recurrence relation gives:
x^n = 2xⁿ⁻¹ - xⁿ⁻² + 2.

Dividing through by xⁿ⁻², we get:
x² = 2x - 1 + 2/xⁿ⁻².

Rearranging terms, we have:
x² - 2x + 1 = 2/xⁿ⁻².

Multiplying through by xⁿ⁻², we obtain:
x^(n) - 2xⁿ⁻¹ + xⁿ⁻² = 2.

The characteristic equation is now:
x² - 2x + 1 = 0.

Factoring the equation, we find that:
(x - 1)² = 0.

This means that x = 1 is a repeated root of the characteristic equation.

To find the general solution, we use the form T(n) = (An + B)(1)ⁿ.

Substituting T(0) = 1 and T(1) = 3, we get:
T(0) = (A(0) + B)(1)⁰ = 1, which implies A + B = 1,
T(1) = (A(1) + B)(1)¹ = 3, which implies A + B = 3.

From these equations, we can solve for A and B as follows:
A + B = 1,
A + B = 3.

Subtracting the second equation from the first, we have:
0 = 2.

This implies that the system of equations has no solution. Hence, the recurrence relation T(n) = 2T(n - 1) - T(n - 2) + 2 does not have a closed form solution.

Regarding the second part of your question, T(n) = O(g(n)) if there exist constants c and n0 such that T(n) ≤ c * g(n) for all n ≥ n0.

Let's consider g(n) = n³. We need to determine whether there exist constants c and n0 such that T(n) ≤ c * n³ for all n ≥ n0.

Since T(n) does not have a closed form solution, we cannot determine whether T(n) = O(g(n)) without further information or analysis. Therefore, we cannot provide a conclusion about T(n) = O(g(n)) in this case.
