Scenario 6.4: A new drug has been developed to assist insomniacs with their sleeping conditions. This new drug (Snorlax) was tested on a sample of 20 participants who suffer from insomnia. Prior to taking the drug, participants were monitored on how many hours of sleep that had each week. Participants were then given Snorlax to take every night and the number of hours slept for the following week was recorded. The researchers wanted to determine if Snorlax had an effect on the number of hours participants spent asleep per week. Using the table below. answerthe questions that follow. (use a=0.01) Without Snorlax With Snorlax Difference (D) Mean (hrs per week) 2795 29.60 1.65 Std. Deviation 4.85 2.91 2.99 Question 47 1 pts Based on scenario 6.4, state the appropriate statistical test. Explain why you came to this conclusion. The proper statistical test for scenario 6.4 is [ Select ] because [ Select ] Question 48 2 pts For scenario 6.4, match bellow to select the correct null and alternative hypotheses. HO: [ Choose ] Ha: [ Choose ] Question 49 2 pts Using the critical value method, obtain a test statistic for scenario 6.4. Give your answer using 2 decimal points and a=0.01.Question 50 1 pts The degrees of freedom for scenario 6.4 are: Question 51 1 pts The critical value for this test in scenario 6.4 is: (Give your answer using 4 decimal points). Question 52 2 pts Conclusion for scenario 6.4: Based on the critical value method we see that the calculated statistics is (|=|less than|more than|smaller than|bigger than|larger than same as) the critical value so we (fail to reject | reject | accept | approve ) then null hypothesis and conclude that there (is|are|is not|is no|are no|exist|exist no|exist not) significant difference between the sample and population mean for insomnia taking the new drug Snorlax.
