What is the appropriate z a value for a 75.4 % confidence interval for u? Round your response to at least 2 decimal places. Number
(b) What z-score is used for a 92% confidence interval? Round your answer to two decimal places. (c) What z-score is used for a 91% confidence interval? Round your answer to two decimal places.
Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value t Subscript alpha divided by 2, (b) find the critical value z Subscript alpha divided by 2, or (c) state that neither the normal distribution nor the t distribution applies. The confidence level is 90%, sigma is not known, and the histogram of 58 player salaries (in thousands of dollars) of football players on a team is as shown....

Use technology to construct the confidence intervals for the population variance sigma squared and the population standard deviation sigma . Assume the sample is taken from a normally distributed population. cequals 0.95, sequals 38, nequals 20 The confidence interval for the population variance is ( ). (Round to two decimal places as needed.) The confidence interval for the population standard deviation is ( ). (Round to two decimal places as needed.)
