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 27 people who drank ethanol and another group of 21 people given a placebo. The errors for the treatment group have a standard deviation of 0.98​, and the errors for the placebo group have a standard deviation of 0.85. Use a 0.01 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. Sample 1: treatment group, n1 = 27, s1 = 0.98. Sample 2: placebo group: n2 = 21, s2 = 0.85

An investigator analyzed the leading digits from 787 checks issued by seven suspect companies. The frequencies were found to be 387​, 201​, 142​, 70, 71​, 28​, 7​, 16​, and 23​, and those digits correspond to the leading digits of​ 1, 2,​ 3, 4,​ 5, 6,​ 7, 8, and​ 9, respectively. If the observed frequencies are substantially different from the frequencies expected with​ Benford's law shown​ below, the check amounts appear to result from fraud. Use a 0.01 significance level to test for​ goodness-of-fit with​ Benford's law. Does it appear that the checks are the result of​ fraud? Leading Digit: 1 2 3 4 5 6 7 8 9 Actual Frequency: 387 201 142 70 71 28 7 16 23 Benford's Law: 30.1% 17.6% 12.5% 9.7% 7.9% ​ 6.7% ​5.8% ​ 5.1% 4.6%
