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 23.2 26.3 28.2 32.2 22.9 31.5 26.2 30.2 32.3 25.4 Women 19.4 17.4 19.9 28.4 18.5 18.7 20.8 30.3 18.3 17.6 12 Click the icon to view the table of Chi-Square critical values. a. Construct a 95% confidence interval estimate of the standard deviation of BMls for men. < σmen < (Round to two decimal places as needed.) b. Construct a 95% confidence interval estimate of the standard deviation of BMls for women. < σwomen < (Round to two decimal places as needed.) c. Compare and interpret the results. A. Since the intervals do not overlap, the populations appear to have different amounts of variation. B. Since the intervals do not overlap, the populations appear to have amounts of variation that are not substantially different. C. Since the intervals overlap, the populations appear to have different amounts of variation. D. Since the intervals overlap, the populations appear to have amounts of variation that are not substantially different.

For a poll, 43% of 21,944 people polled answered “yes” to the given question. Given that 43% is the best estimate of the population percentage, why would we need a confidence interval? That is, what additional information does the confidence interval provide? Choose the correct answer below. A. Information about the standard deviation of the population. B. Information about the mean of the population. C. Information about the accuracy of the estimate. D. Information about the mean of the sample.
