The required details for mean rate :

(a) H0: µ = 21.62

(b) t = -1.231

p-value = 0.2253

(c) Stop rejecting H0 right now. No longer significantly different from the domestic water tariff in Tulsa, the suggested household water charge per five CCF for the entire USA.

(d) H0: µ = 21.62

Ha: µ ≠ 21.62

t = -1.231

check statistic ≥ 2.020

Don't dismiss H0 any longer. The suggested five CCF residential water charge for the entirety of the USA is no longer significantly different from the five CCF residential water tariff in Tulsa.

The P-value is higher at 0.05, the level of significance. The impact in this instance is negligible. The attempt to reject the null hypothesis failed.

The conclusion is that there is insufficient statistical support to determine whether other American cities have a different mortality rate than Tulsa.

The crucial values for t at this level of significance are t=2.019.

Given that the statistic t = -1.15 is inside the acceptance range in this case, the null hypothesis is not disproved.

Given that there is table giving the values of x and y,

The equation of a line is linear in the variables x and y which represents the relation between the coordinates of every point (x, y) on the line. i.e., the equation of line is satisfied by all points on it.

The equation of a line can be formed with the help of the slope of the line and a point on the line.

The slope of the line is the inclination of the line with the positive x-axis and is expressed as a numeric integer, fraction, or the tangent of the angle it makes with the positive x-axis.

The point refers to a point on the with the x coordinate and the y coordinate.

Considering the two points, (0, 4) and (1, 7),

By using these points, we will find the line by which the points are passing,

So, we know that equation of a line passing through two points is given by,

y - y₁ = y₂ - y₁ / x₂ - x₁ (x - x₁)

The function represents exponential decay, meaning that the population is decreasing over time.

Exponential growth and decay are mathematical concepts that describe the increase or decrease of a quantity over time.  

Exponential decay occurs when the rate of decrease of a quantity is proportional to the current value of the quantity.

The formula for exponential decay is given:

y = a(1 - r)^t

where y is the final value, a is the initial value, r is the decay rate, and t is the time.

Here we have

The population of a country is modeled by the function

f(x) = 375(1 − 0.002)x.

The given function is f(x) = 375(1 − 0.002)x,

which can be written in form f(x) = a(1 + r)x,

where a = 375 and r = -0.002.

The formula a(1 + r)x represents exponential growth if r is positive and exponential decay if r is negative.

In this case, r = -0.002, which is negative.

Therefore,

The sum of Peter, Richard, and John's ages is 191.

We know that the ratio of Peter's age to Richard's age is = 5/8 --(i)

The ratio of John's age to Peter's age is = 7/12 --(ii)

Similarly, the ratio of John's age to Richard's age is = (5*7)/(8*12)= 35/96 -(iii)

Using the value of (i),(ii),(iii), we get -

Age of Peter = (5*12)/(8*12) = 60/96

= 60 years of age

Age of John = (7*5)/(12*5) = 35/60

=35 years of age

From the value of (iii), since no one is over 100 years of age, the age of Richard= 96 years of age

Hence the sum of their ages is = 96+35+60

= 191

Therefore, we know that the sum of their ages is 191.

Answer:

The probability that the industry will locate in both cities is 0.4. The probability that it will locate in either Shanghai or Beijing or both is 0.8.

Step-by-step explanation:

The probability that the industry will locate in both cities is 0.41. The probability that it will locate in either Shanghai or Beijing or both is 0.81. We can use the formula P(A and B) = P(A) * P(B|A) to calculate the probability of an event occurring in both cities. Let A be the event that the industry locates in Beijing and B be the event that it locates in Shanghai. Then, P(A or B) = P(A) + P(B) - P(A and B) = 0.8. Therefore, P(A and B) = P(A) * P(B|A) = (0.4 * 0.4)/0.8 = 0.2. The probability that the industry will not locate in either city is given by P(neither A nor B) = 1 - (P(A) + P(B) - P(A and B)) = 1 - (0.4 + 0.4 - 0.2) = 0.2.

After three years with a monthly deposit of $250 and an APR of 8.4%, you will have approximately $10,093.46 towards the purchase of a boat.

To calculate the amount you will have towards the purchase of a boat after three years with an APR (Annual Percentage Rate) of 8.4% and monthly deposits of $250, we can use the formula for the future value of a series of regular deposits:

FV = P * [(1 + r)^n - 1] / r

Where:

FV is the future value of the deposits

P is the monthly deposit amount ($250)

r is the monthly interest rate (8.4% / 12 = 0.007)

n is the number of periods (3 years * 12 months = 36)

The probability that if an individual man is randomly​ selected, his hip breadth will be greater than 16.6 in. is 0.0509.

A z-table also known as the standard normal distribution table, helps us to know the percentage of values that are below (or to the left of the Distribution) a z-score in the standard normal distribution.

As the distribution is normally distributed, with a mean of 14.8 In., while the standard deviation is 1.1 inches. Therefore,

A.) The probability that if an individual man is randomly​ selected, his hip breadth will be greater than 16.6 in.

\(P(X > 16.6)=P(z > 16.6)\)

                    \(=1-P(z < 16.6)\)

                    \(=1-P\huge \text(\dfrac{16.6-\mu}{\sigma}\huge \text)\)

                    \(=1-P\huge \text(\dfrac{16.6-14.8}{1.1}\huge \text)\)

                    \(=\sf 1- 0.9491\)

                    \(\sf =0.0509\)

Hence, the probability that if an individual man is randomly​ selected, his hip breadth will be greater than 16.6 in. is 0.0509.

B.) The probability that 127 men have a mean hip breadth greater than 16.6 in.

\(P(X > 16.6)=P\huge \text(z > \dfrac{16.6-14.8}{\frac{1.1}{\sqrt{127} } } \huge \text)\)

                    \(=P(z > 18.44)\)

                    \(=1-P(z\leq 18.44)\)

                    \(\sf =1-0.9995\)

                    \(\sf =0.0005\)

Hence, the probability that 127 men have a mean hip breadth greater than 16.6 in. is 0.0005.

Complete parts (a) through (c) below. (a) Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.6 in. The probability is (Round to four decimal places as needed.) (b) If a plane is filled with 127 randomly selected men, find the probability that these men have a mean hip breadth greater than 16.6 in. The probability is (Round to four decimal places as needed.) (c) Which result should be considered for any changes in seat design: the result from part (a) or part (b)? The result from should be considered because

(a) To find the probability of a randomly selected man having a hip breadth greater than 16.4 inches, we calculate the z-score and use the standard normal distribution.

(b) To find the probability of the mean hip breadth of 111 randomly selected men being greater than 16.4 inches, we use the Central Limit Theorem and calculate the z-score for the sample mean.

(c) The result from part (a) should be considered for seat design changes as it focuses on individual comfort and fit, while the result from part (b) considers the mean hip breadth of a group, which may not represent individual needs.

(a) To find the probability that a randomly selected man will have a hip breadth greater than 16.4 inches, we can use the standard normal distribution. First, we calculate the z-score using the formula: z = (x - μ) / σ, where x is the value we're interested in (16.4 inches), μ is the mean (14.1 inches), and σ is the standard deviation (1 inch).

Plugging in the values, we get: z = (16.4 - 14.1) / 1 = 2.3.

Next, we look up the z-score in the standard normal distribution table or use a calculator to find the corresponding probability. In this case, the probability associated with a z-score of 2.3 is approximately 0.0228.

Therefore, the probability that a randomly selected man will have a hip breadth greater than 16.4 inches is 0.0228 (or approximately 2.28%).

(b) To find the probability that the mean hip breadth of 111 randomly selected men will be greater than 16.4 inches, we use the Central Limit Theorem. According to the Central Limit Theorem, the distribution of sample means will approach a normal distribution, regardless of the shape of the original population, as the sample size increases.

Since the sample size is large (n = 111), we can assume that the distribution of the sample mean will be approximately normal. We calculate the standard error of the mean using the formula: σ / sqrt(n), where σ is the standard deviation of the population (1 inch) and n is the sample size (111).

Plugging in the values, we get: standard error = 1 / sqrt(111) ≈ 0.0947.

Next, we calculate the z-score for the sample mean using the formula: z = (x - μ) / (σ / sqrt(n)), where x is the value of interest (16.4 inches), μ is the population mean (14.1 inches), σ is the population standard deviation (1 inch), and n is the sample size (111).

Plugging in the values, we get: z = (16.4 - 14.1) / (1 / sqrt(111)) ≈ 24.17.

We then look up the z-score in the standard normal distribution table or use a calculator to find the corresponding probability. In this case, the probability associated with a z-score of 24.17 is very close to 0 (practically negligible).

Therefore, the probability that the mean hip breadth of 111 randomly selected men will be greater than 16.4 inches is approximately 0 (or extremely close to 0).

(c) When considering changes in seat design, the result from part (a) should be considered rather than the result from part (b). This is because individual passengers occupy the seats, and their individual comfort and fit should be the primary concern. The result from part (a) provides information about the probability of a randomly selected man having a hip breadth greater than 16.4 inches, which directly relates to the individual passenger's experience. On the other hand, the result from part (b) considers the mean hip breadth of a group, which may not accurately represent the needs and comfort of individual passengers.

The correct question should be :
