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 23 people who drank ethanol and another group of 23 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 0.86. Use a 0.05significance 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 is the conclusion for this test

Reject/fail to reject H0. There is insufficient/sufficient evidence to support the claim that the treatment group has errors that vary significantly more than the errors of the placebo group.
