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 28 people who drank ethanola another group of 28 people given a placebo The errors for the treatment group have a standard deviation of 2 10 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 OA Hoo 0 H 00 OC Ho 00 H 0 Identify the test statistic Round to two decimal places as needed Use technology to identify the P value Round to three decimal places as needed OB Ho 0 H 0 0 OD Hoo H 00
