In the course of designing theater seats, the sitting heights (in mm) of a simple random sample of 12 adult women is obtained. The sample mean is 834 mm and sample standard deviation is 34.98 mm. a. Assuming that sample is obtained from a population with a normal distribution, construct a 95% confidence interval estimate for o, the population standard deviation of sitting height of adult women. b. Does the confidence interval contain 35 mm, which is believed to be the standard deviation of sitting heights of women?
