Prоf Reа's Exаm Questiоn 7. A study wаs cоnducted to investigate the effectiveness of yoga in reducing stress. Results for randomly selected subjects are shown in the table which you can also find here as a google sheet that can be used to copy and paste sets into desmos. A lower score indicates less stress. The differences have a normal distribution. Subject Stress Before Meditation Stress After Meditation Difference (After minus Before) A 6.4 6.8 B 6.5 2.4 C 9.1 7.4 D 10.3 8.5 E 11.3 8.1 F 8.1 6.1 G 6.3 3.4 H 11.6 2 Compute the differences (After minus Before). Explain why this is an example of a paired sample. Compute the sample mean difference rounded to three decimal places using desmos. Write the function used in desmos to calculate this statistic. Compute the sample standard deviation rounded to three decimal places using desmos. Write the function used in desmos to calculate this statistic. Are the stress measurements, on average, lower after yoga? Test at a 5% significance level. Show all four steps of a hypothesis test to earn full credit. Round all calculated values to three decimal places.
