15) BMI (Body Mass Index) is one useful medical measurement, and a BMI of 30 or higher classifies a person as obese. Follows is a SRS (from a population that is normally distributed) of BMI readings for 22 women: 19.6, 23.8, 19.6, 29.1, 25.2, 214, 22.0, 27.5, 33.5, 20.6, 29.9, 17.7, 24.0, 28.9, 37.7, 18.3, 19.8, 29.8, 29.7, 31.7, 23.8, and 44.9. Use a 0.05 significance level to test the claim that these women come from a population that would not be classified obese. State the null and alternative hypotheses. Hop ≤ 30 a) Ha:μ> 30 Ho:μ 2.30 b) Ha: <30 16) See problem 15. State the critical value. a)-2.080 b) 1.721 17) See problem 15. Calculate the test statistic. a)-1.721 b) 6.809 18) See problem 15. Calculate the pvalue. a) 0.0500 b) 0.0042 Ho: u = 30 c) Hap 30 c) 12.080 c)-2.552 I c)-2.552 19) See problem 15. Calculate the appropriate confidence interval. a) (23.8, 28.8) b) (23.3, 29.3) c) (22.6, 30.0) d) Ho:μ> 700 Ha:μ ≤ 700 d)-1.721 d) 0.0092 d) 0.0093 d) (22.2, 30.4) 20) See problem 15. State the technical conclusion based on the traditional method. a) The test statistic is further from zero than is the critical value; FTR Ho. b) The test statistic is closer to zero than is the critical value; Reject Ho. c) The test statistic is further from zero than is the critical value; Reject Ho. d) The test statistic is closer to zero than is the critical value; FTR Ho.
