Suppose a survey of a random sample of 100 smokers, conducted by the Department of Health, suggests that the mean number of cigarettes a person smokes in a day in Smokelandia (Y) is 2.72 and the standard deviation (sy) is 0.58. The Department of Health is concerned about the results of the survey and wants to test whether the mean number of cigarettes a person smokes in a day is 2.52 or not. The test statistic associated with the above test is 3.45 (Round your answer to two decimal places.) If the Department of Health uses a 5% significance level, the test statistic suggests that we reject smokes in a day is 2.52. Suppose the Department of Health decides to reject the null hypothesis (Ho) if |Y-2.52| > > 0.08. The size of the above test is 0.17. (Round your answer to two decimal places.) If μ = 2.68, the power of the above test is (Round your answer to two decimal places.) the hypothesis that the mean number of cigarettes a person Suppose a survey of a random sample of 100 smokers, conducted by the Department of Health, suggests that the mean number of cigarettes a person smokes in a day in Smokelandia (Y) is 2.72 and the standard deviation (sy) is 0.58.
