Description: Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t,2, (b) find the critical value z12, or (c) state that neither the normal distribution40-nor the t distribution applies.30-

It is given that the histogram of 61 player salaries of football players on a team. From the histogram, it looks like right-skewed. The given data does not follow t-distribution and normal distribution. Therefore, the correct option is c. Neither the normal distribution nor the t-distribution applies. The value of n is 1058 and the value of x is 597.a) Calculate the point estimate of all population proportion p is as follows: Therefore, the point estimate of all population proportion p is 0.564. b) Calculate the z-critical value using Excel is as follows: Calculate the value of the margin of error is as follows: Therefore, the value of the margin of error is 0.025.c) Calculate the confidence interval is as follows: Therefore, the confidence interval is 0.539 < p < 0.589. d) There is a 90% chance that the true value of the population proportion will fall between the lower bound and the upper bound.
