Identify test static

Homework: 9.4 HW HW Score: E - Two Variances or Question 6, 38.57%, 27 of Standard 9.4.15-T 70 points Deviations Part 2 of 4 Points: 0 Save of 10 The accompanying data set lists full IQ scores for a 79 71 90 111 92 97 85 91 2 random sample of subjects with medium lead levels Medium 91 100 83 86 92 72 77 78 in their blood and another random sample of subjects with high lead levels in their blood. Use a 0.05 significance level to test the claim that IQ scores of 80 75 93 75 80 96 83 88 High subjects with medium lead levels vary more than IQ 88 80 101 85 85 82 79 scores of subjects with high lead levels. Let sample 1 be the sample with the larger sample variance, and let sample 2 be the sample with the smaller sample variance. What are the null and alternative hypotheses? O A. HO: 07 OB. Ho: 02 707 H1:09 7 02 H1 : 01 C. Ho: 07 =07 OD. HO:07 =03 2 H 1: 0> 02 H1: 09
