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 signicance 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 smalier sample variance.
