5. A study was performed to test a new treatment for autism in children. In order to test the new method, parents of children with autism were asked to volunteer for the study in which 9 parents volunteered their children for the study. The children were each asked to complete a 20 piece puzzle. The time it took to complete the task was recorded in seconds. The children then received a treatment [20 minutes of Yoga] and were asked to complete a similar but different puzzle. The data from the study is below: Child Before Aft: r 1 35 3'5 2 3'0 3 40 50 4 65 5 80 20 6 T5 55 ".r' 55 3 20 25 9 TD 30 a. Perform a signed rank test by hand showing the nai table with the absolute differences, the signs and the ranks. Also, show your calculation of the zstatistic for each case. b. Conduct the six step hypothesis test using your calculations from above to test the claim that the yoga treatment was effective in reducing the time to finish the puzzle. c. Use 5A5 to nd the test statistic and pvalue for a paired ttest of this data to test. d. Conduct the six step hypothesis test using your paired ttest analysis test the claim that the yoga treatment was effective in reducing the time to finish the puzzle. e. Use your data from above to construct a \"complete analysis" of the test that you feel is most appropriate to test the claim that the yoga treatment was effective in reducing the time to nish the puzzle
