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, 252, 214, 22.0, 27.5, 33.5, 206, 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 the population variance of this group is greater than 35.0. State the null and alternative hypotheses Hod=35.0 Ha:a¹35.0 b) Heids 35.0 Ha:a²> 35.0 16) See problem 15. State the critical value(s). a) 10.283, 35.479 b) 33.924 17) See problem 15. Calculate the test statisti a) 0.795 b) 26.431 35.0. Hot350 Ha: 35.0 c) 32.671 c) 4.086 d) b) The test statistic is external to the critical valuels); FTR Ho. c) The test statistic is not external to the critical value(s): Reject Ho. d) The test statistic is not external to the critical values); FTR Ho Hoa e350 Hata 235.0 d) 11.591, 32.671 18) See problem 15. State the technical conclusion based on the traditional method. a) The test statistic is external to the critical value(); Reject Ho. d) 27,820 19) See problem 15. State the non-technical conclusion. a) There is sufficient evidence to warrant rejection of the claim that the population variance of this group is greater than 35.0. b) There is not sufficient evidence to warrant rejection of the claim that the population variance of this group is greater than 35.0 c) The sample data support the claim that the population variance of this group is greater than d) There is not sufficient sample evidence to support the claim that the population variance of this group is greater than 35.0
