Question
Male BMI Female BMI H2 Given in the table are the BMI statistics for random samples of men and women. Assume that the two samples are independent simple u random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) and (b) below. Use a 0.05 significance level for both parts. n 50 50 27.7774 24.5556 S 8.421694 4.418734 a. Test the claim that males and females have the same mean body mass index (BMI). What are the null and alternative hypotheses? O B. Ho: H1 # H2 H1: H1 <H2 O A. Ho: H1 = H2 H1: 41 # H2 O C. Ho: H12 H2 H1: H1 <H2 D. Ho: H1 = H2 H1: H1 > H2 The test statistic, t, is (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.)
