# Question: a Given the following information determine the 90 confidence interval

a. Given the following information, determine the 90% confidence interval estimate of the population mean using the sample median.

Sample median = 500, σ = 12, and n = 50

b. Compare your answer in part (a) to that produced in part (c) of Exercise 10.12. Why is the confidence interval estimate based on the sample median wider than that based on the sample mean?
