Designing Theater seats- In the course of sesigning theater seats, the sitting heights(in mm) of a simple random sample of adult women is obtained, and the results are listed below(based on anthropometric survey data from Gordon, Churchill, et al). Use the sample data to construct a 95% confidence interval estimate of the σ, the standard deviation os sitting heights of all women. Does the confidence interval contain the value of 35 mm, which is believed to be the standard deviation of sitting heights of women?
