A person's body mass index (BMI) is computed by dividing the weight (kg) by the square of height (m). The accompanying table contains the BMI statistics for random samples of males and females. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Let population 1 be females. Complete parts (a) through (c) below. E Click the icon to view the table of statistics. O A. Ho: H1 = H2 H,: Hy> H2 O B. Ho: H1 = H2 OC. Ho: H1> H2 H,: H1 = H2 O D.

The P-value is (Round to three decimal places as needed.) State the conclusion for the test. v the null hypothesis. There sufficient evidence to warrant rejection of the claim that females and males have the same mean BMI. b. Construct a confidence interval appropriate for testing the claim in part (a).
