Round to three decimal places. For a confidence level of 99%, find the critical z

The confidence level is 99% , o= 4178 thousand dollars, and the histogram of 59 player salaries of football players. Find the critical value za/2 and ta/2

Use the t-distribution to find a confidence interval for a mean given the relevant sample results. Give the best point estimate for μ, the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is approximately normally distributed. A 99% confidence interval for using the sample results = 88.8, s = 31.5, and n = 15 Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. point estimate = i margin of error = i The 99% confidence interval is i to i

q21- The z value for a 95% confidence interval estimate is: Select one: a. 2.12. b. 1.82. c. 2.00. d. 1.96.

Find the critical t value that corresponds to 95% confidence, Assume 29 degrees of freedom (two tailed) Round to 3 decimals

Construct the indicated confidence interval for the population mean y using the t- distribution. Assume the population is normally distributed. C=0.99, x=12.6,  s= 0.81, n=17
