Loomi is interested in the amount of television that teenagers watch at homeduring the weekends. She asks the parents of 12 teenagers how many hours, onaverage, their children spend watching TV every weekend. She wants to convertthe number of hours of TV watched into z-scores. She would also like to view agraphical representation of the distribution. These raw scores are presented tothe right.TV668674481010141 Use jamovi to generate z-scores for these data.Provide a screenshot of your data view showing thesez-scores.Paste a histogram (overlaid with a density curve) ofthe raw data. How would you describe the shape ofthe distribution ?What is the z-score for a teenager who watched 7hours of TV in this sample?Given what you know about this sample, how wouldyou describe the TV watching habits of a teenagerwho watched 7 hours of TV ?

Jocelyn believes that the amount of sleep she tends to get on weekends differs from the amount of sleep she tends to get during the school week. To investigate this claim, she randomly selects 10 weekend days and 10 school days. She consults her smart watch to determine the number of hours she slept for each of the selected days. Here are the data. School week: 7, 7.5, 8, 6.5, 8, 7.5, 7, 6.5, 7, 8Weekend: 9.5, 9.5, 8.25, 8.5, 7.5, 10.25, 8, 7, 9.5, 10 Jocelyn would like to determine if these data provide convincing evidence that the true mean amount of sleep she gets on the weekend differs from the true mean amount of sleep she gets during the school week. She tests H0: μS – μW = 0, Ha: μS – μW ≠ 0, where μW = the true mean amount of sleep Jocelyn gets on the weekend and μS = the true mean amount of sleep she gets during the school week. The conditions for inference are met. What are the values of the test statistic and P-value for a t-test about a difference in means? Find the…
