Identify the test static

Homework: 9.4 HW - Two HW Score: 31.43%, 22 of 70 O Variances or Standard Question 4, 9.4.9-T points Part 2 of 4 Deviations Points: 0 of 10 Save Researchers conducted an experiment to test the effects of alcohol. Errors were recorded in a test of visual and motor skills for a treatment group of 21 people who drank ethanol and another group of 21 people given a placebo. The errors for the treatment group have a standard deviation of 2.30, and the errors for the placebo group have a standard deviation of 0.73. Assume that the two populations are normally distributed. Use a 0.05 significance level to test the claim that both groups have the same amount of variation among the errors. 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? 32 =02 A. HO: 07 = OB.
