00:07:14A sleep disorder specialist wants to test the effectiveness of a new drug that is reported to increase the number of hours of sleep patients get during the night. To do so, the specialist randomly selects nine patients and records the number of hours of sleep each gets with and without the new drug. The results of the two-night study are listed below. Using this data, find the 90% confidence interval for the true difference in hours of sleep between the patients using and not using the new drug.Let d = (hours of sleep with the new drug)-(hours of sleep without the new drug). Assume that the hours of sleep are normally distributed for the population of patients both before and after taking the new drug.PatientHours of sleep without the drug5.523456.9 2 2.2 3.763.578 93.6 2.4 4.5Hours of sleep with the new drug17.8 8.1 5 4.1 5.3 6.2 4.3 4.9 7.5Copy DataStep 2 of 4: Find the critical value that should be used in constructing the confidence interval.

Not in excess of .2 In excess of .2 but not in excess of .3 In excess of .3 but not in excess of .4 In excess of .4 but not in excess of .6 In excess of .6

Fisher's Least Significant Difference (LCD) method examines the pairwise difference in the mean values of three treatment groups at a 0.010.01 level of significance. Determine the critical value if the total number of observations in all the samples is 2020. Round your answer to three decimal places.

You may need to use the appropriate technology to answer this question. Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost-estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours). 1.81.62.52.12.42.32.63.01.42.3 With a 0.05 level of significance, test to see whether the mean tree-planting time differs from two hours. (a) State the null and alternative hypotheses. H0: ???? ≤ 2 Ha: ???? > 2 H0: ???? ≥ 2 Ha: ???? < 2 H0: ???? > 2 Ha: ???? ≤ 2 H0: ???? = 2 Ha: ???? ≠ 2 H0: ???? < 2 Ha: ???? ≥ 2 (b) Compute the sample mean. (c) Compute the sample standard deviation. (Round your answer to three decimal places.) (d) What is the test statistic? (Round your answer to three decimal places.) What is the p-value? (Round your answer to four decimal places.) p-value = (e) What is your conclusion? Do not reject H0. We can conclude that the mean tree-planting time differs from two hours. There is a reason to change from the two hours for cost estimating purposes.Reject H0. We cannot conclude that the mean tree-planting time differs from two hours.
