Quiz: Quiz 4 (Chapter 9) Question 10 of 10 This question: 1 point(s) possible Submit quiz Researchers conducted an experiment to test the allects of alcohol. Errors were recorded in a test of visual and motor skills for a treatment group of 22 people who drank ethanol and another group of 22 people given a placebo. The errors for the treatment group have a standard deviation of 2.40, and the errors for the placebo group have a standard deviation of 0 86. Use a 0.05 significance level to test the claim that the treatment group has errors that vary significantly more than the errors of the placebo group Assume that the two populations are normally distributed What are the null and alternative hypotheses? OB Ho 4 202 H1 07 402 OC Ho 07 103 OD. Ho 3 =03 H1 01 =62 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.) What is the conclusion for this hypothesis test? O A. Reject He There is sufficient evidence to support the claim that the treatment group has errors that vary significantly more than the errors of the placebo group. O B. Fad to reject Ho. There is insufficient evidence to support the claim that the treatment group has errors that vary significantly more than the errors of the placebo group. O C. Fail to reject Ho There is sufficient evidence to support the claim that the treatment group has errors that vary significantly more than the errors of the placebo group. O D. Reject Ho. There is Insufficient evidence to support the claim that the treatment group has errors that vary significantly more than the errors of the placebo group. Submit quiz
