8. Sampling Distributions & Confidence Intervals: Proportion / Confidence Intervals for Population Variance / Problem 4
Problem 4

A random sample of 1010 adult males had their total cholesterol levels (in mg/dL\(\text{mg/dL}\)) measured:
180,190,195,200,205,210,195,200,205,190180,190,195,200,205,210,195,200,205,190
Use this sample to construct a 95%95\% confidence interval estimate of the population standard deviation of cholesterol levels.
