Q3: [25] Multiple Sclerosis (Manual Calculation and SPSS) Multiple sclerosis is a chronic disease that affects the central nervous system, which is the brain, spinal cord, and optic nerves. This can lead to a wide range of symptoms throughout the body. In a clinic trial of a new intervention for Multiple Sclerosis (MS), a group of 10 patients (called "Treatment" group) with MS are given the new treatment/intervention, while another group of 10 patients with MS on the waiting list (called "Control Group") do not receive any treatment/intervention. The memory scores recorded for the two groups are in the following table. Treatment Group |Control Group 14 18 7 10 12 13 11 15 14 15 5 12 4 12 10 10 12 Assume the assumptions of normality are satisfied. Do the data provide sufficient evidence at 5% level of significance that the treatment/intervention improves the memory performance? (a) [4] State the null and alternative hypotheses. (b) [8] Perform the hypothesis test using critical value (CV) approach at 5% level of sig- nificance. (Manual Calculation) (c) [13]Assuming the level of significance, o = .05, carry out the hypothesis test in SPSS using p-value approach. Include the snapshot of SPSS data set and SPSS output. Do you have the same decision as critical value approach performed in step (b)? (SPSS)
