The body mass index (BMI) for a sample of men and a sample of women are given below Assume the samples are simple random samples obtained from populations with normal distributions. Men 308 Women 17.6 24.5 19.7 24.6 192 30.3 34.2 23.4 28.3 22.9 32.1 18.1 27.8 35.7 22.6 26 9 18.1 Click the icon to view the table of Chi-Square critical values. a. Construct a 99% confidence interval estimate of the standard deviation of BMIs for men. 2.04 < 7.52 men (Round to two decimal places as needed.) b. Construct a 99% confidence interval estimate of the standard deviation of BMIs for women women (Round to two decimal places as needed.)
