Answer

K 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. Click the icon to view the table of statistics. D. Ho: H1 H2 H₁: H1 H2 Statistics Female BMI: n = 70 x=29.35 S=7.18 Male BMI: n=82 x=28.45 S=5.53 The test statistic is (Round to two decimal places as needed.) The P-value is (Round to three decimal places as needed.) State the conclusion for the test. the null hypothesis. There Print Done 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). The % confidence interval…

Qualifying Test Scores To qualify for a medical study, an applicant must have a systolic blood pressure in the 60% of the middle range. If the systolic blood pressure is normally distributed with a mean of 120 and a standard deviation of 5, find the upper and lower limits of blood pressure a person must have to qualify for the study. Round final answers to 1 decimal place and intermediate :-value calculations to 2 decimal places. Applicants must have a lower blood pressure limit of and an upper blood pressure limit of to qualify for the study. Ol
