Step-by-step explanation:

The mean weight of the team was found to be 222.47 pounds. The standard deviation was 28.32 pounds. 3 standard deviations below the mean were 136.83 pounds. Player A was approximately 0.20 standard deviations above the mean.

(i) Mean:

mean = (sum of all weights) / (number of weights) = (177 + 203 + 211 + 211 + 232 + 205 + 185 + 185 + 178 + 210 + 206 + 212 + 184 + 174 + 185 + 242 + 188 + 212 + 215 + 247 + 241 + 223 + 220 + 260 + 245 + 259 + 278 + 270 + 280 + 295 + 275 + 285 + 290 + 272 + 273 + 280 + 285 + 286 + 200 + 215 + 185 + 230 + 250 + 241 + 190 + 260 + 250 + 302 + 265 + 290 + 276 + 228) / (55) = 222.47

So, the mean weight of the team members of Football Team A was approximately 222.47 pounds.

(ii) Standard deviation:

We need to calculate the deviation from the mean for each weight and then find the square of the deviations. We can then find the sum of the squared deviations, divide by the number of weights minus 1, and then find the square root of the result.

Deviation from the mean:

177 - 222.47 = -45.47,

203 - 222.47 = -19.47,

211 - 222.47 = -11.47, and so on till,

228 - 222.47 = 5.53

Squared deviation:

(-45.47)^2 = 2070.5489,

(-19.47)^2 = 379.3409,

(-11.47)^2 = 131.4409, and so on till,

(5.53)^2 = 30.6409.

Sum of squared deviations:

sum = 2070.5489 + 379.3409 + 131.4409 + ... + 30.6409

sum = 30589.6409

standard deviation = square root of [(sum of squares of deviations from the mean) / (number of observations - 1)]

standard deviation = square root of [(30589.6409) / (55 - 1)]

standard deviation = 28.32

So, the standard deviation of the weights of the team members of Football Team A was approximately 28.32 pounds.

(iii) 3 standard deviations below the mean:

3 standard deviations below the mean = mean - (3 * standard deviation) = 222.47 - (3 * 28.32) = 136.83

So, a weight that is 3 standard deviations below the mean is approximately 136.83 pounds.

(iv) Player A's weight in terms of standard deviations:

Player A's weight = 228 pounds

Player A's deviation from the mean = 228 - 222.47 = 5.53

Player A's weight in terms of standard deviations = 5.53 / 28.32 = 0.20

So, Player A was approximately 0.20 standard deviations above the mean.

We would expect to find the middle 68% of the average amounts of nicotine in a sample of size 41 to be between approximately 0.901 g and 0.991 g by using properties of the normal distribution.

To find the range in which you would expect to find the middle 68% of amounts of nicotine in these cigarettes, we can use the properties of the normal distribution.

Given:
Mean (μ) = 0.946 g
Standard deviation (σ) = 0.289 g

For a normal distribution, approximately 68% of the data falls within one standard deviation of the mean. Therefore, we can expect the middle 68% of amounts of nicotine to fall within the range:

μ ± σ

Substituting the given values:

0.946 ± 0.289

To calculate the range, we have:

Lower bound = 0.946 - 0.289 ≈ 0.657 g
Upper bound = 0.946 + 0.289 ≈ 1.235 g

Therefore, we can expect to find the middle 68% of amounts of nicotine in these cigarettes to be between approximately 0.657 g and 1.235 g.

Now, if we were to draw samples of size 41 from this population, the standard deviation of the sample mean (also known as the standard error) can be calculated as:

Standard error (SE) = σ / √n

where σ is the population standard deviation and n is the sample size.

Substituting the given values:

SE = 0.289 / √41 ≈ 0.045 g

To find the range in which we would expect to find the middle 68% of the sample means, we multiply the standard error by 1 to capture approximately 68% of the data, giving us:

Lower bound = μ - SE ≈ 0.946 - 0.045 ≈ 0.901 g
Upper bound = μ + SE ≈ 0.946 + 0.045 ≈ 0.991 g

Therefore, we would expect to find the middle 68% of the average amounts of nicotine in a sample of size 41 to be between approximately 0.901 g and 0.991 g.

The required rate of return (or minimum acceptable rate of return) is 20 percent. If the net cash flows are $15,000 per year for ten years, the total cash flow is $150,000. The project's cost is $47,500. We can now apply the net present value formula to determine whether or not the project is feasible.

Net Present Value (NPV) = Cash flow / (1 + r)^n - Cost Where, r is the discount rate, n is the number of years, and Cost is the initial outlay.

Net Present Value = 150000 / (1 + 0.20)^10 - 47500

Net Present Value = $67,482.22

Since the NPV is positive, the project is feasible. When calculating net present value, it's important to remember that a positive NPV implies that the project is expected to generate a return that exceeds the cost of capital, whereas a negative NPV indicates that the project is expected to generate a return that is less than the cost of capital, and as a result, it should be avoided.

The contribution of the Monday absences to the calculation of the chi-square test statistic would depend on the size of the observed and expected frequencies in that cell relative to the other cells in the table.

Without more information about the specific claim being tested and the data being analyzed, it is difficult to provide a precise answer. However, in general, if the claim being tested involves a comparison of the frequency of absences on Mondays to the frequency of absences on other days of the week, then the number of Monday absences would likely be one of the variables included in the calculation of the chi-square test statistic.

The chi-square test is a statistical test that is used to determine if there is a significant association between two categorical variables. In order to perform the test, the observed frequencies of each category of each variable are compared to the expected frequencies, which are calculated based on the assumption of independence between the variables. The difference between the observed and expected frequencies is then squared, divided by the expected frequency, and summed across all categories of both variables to obtain the chi-square test statistic.

If the claim being tested involves a comparison of the frequency of absences on Mondays to the frequency of absences on other days of the week, then the number of Monday absences would likely be one of the categories of one of the variables included in the calculation of the chi-square test statistic.

The answer for length of BC is 4.0 feet.

The account balance after 15 years with an initial investment of $15,000, compounded quarterly at an interest rate of 1.5%, is $18,899.82.

To calculate the account balance after 15 years with an initial investment of $15,000, compounded quarterly at an interest rate of 1.5%, we can use the formula for compound interest:

A = P(1 + r/n)ⁿᵇ

where:

A = final amount (account balance)

P = principal amount (initial investment)

r = annual interest rate (as a decimal)

n = number of times the interest is compounded per year

b = time (in years)

Plugging in the given values, we get:

A = 15000(1 + 0.015/4)⁴×¹⁵

A = 15000(1 + 0.00375)⁶⁰

A = 15000(1.00375)⁶⁰

A = 15000(1.260655)

A = $18,899.82

Therefore, the account balance after 15 years with an initial investment of $15,000, compounded quarterly at an interest rate of 1.5%, is approximately $18,899.82.

                                                                                 1 0 0]

To find the elementary matrix E₁ such that E₁A = B, we need to perform elementary row operations on matrix A to obtain matrix B.

Let's denote the elementary matrix E₁ as D.

Starting with matrix A:

A = [9 10 1

20 1 11

8 -19 -1]

And matrix B:

B = [8 -19 20

1 11 9

10 1 1]

To obtain B from A, we need to perform row operations on A. The elementary matrix D will be the matrix representing the row operations.

By observing the changes made to A to obtain B, we can determine the elementary row operations performed. In this case, it appears that the row operations are:

Row 1 of A is swapped with Row 3 of A.

Row 2 of A is swapped with Row 3 of A.

Let's construct the elementary matrix D based on these row operations.

D = [0 0 1

0 1 0

1 0 0]

To verify that E₁A = B, we can perform the matrix multiplication:

E₁A = DA

D * A = [0 0 1 * 9 10 1 = 8 -19 20

0 1 0 20 1 11 1 11 9

1 0 0 8 -19 -1 10 1 1]

As we can see, the result of E₁A matches matrix B.
