Arbitron Media Research Incorporated conducted a study of the iPod listening habits of men and women. One facet of the study involved the mean listening time. It was discovered that the mean listening time for a sample of 13 men was 30 minutes per day. The standard deviation was 13 minutes per day. The mean listening time for a sample of 11 women was also 30 minutes, but the standard deviation of the sample was 14 minutes. At the 0.02 significance level, can we conclude that there is a difference in the variation in the listening times for men and women? a. State the null and alternate hypotheses. Ho 02-0₂2 and H4: 0₁²0₂² Ho: 0₁2-0₂2 and H₁: 0₂²=0₂² O Ho: 0₁20₂2 and H₁ 0₂² 0₂² Ho 02 ≤ 0₂² and H₁: 0₁²>0₂² b. State the decision rule. (Round your answer to 2 decimal places.) Reject Ho where F>
c. Compute the value of the test statistic. (Round your answer to 2 decimal places.) The tast statistic is d. Compute the p-value. (Round your answer to 4 decimal places.) p-value e. What is your decision regarding He? Decision Ho Help Sa
f. Interpret the result. We can conclude that there is in the variation in the listening times for men and women. < Prev 2 of 20 Next >
