A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow.

Music and memory Is it a good idea to listen to musicwhen studying for a big test? In a study conducted by some Statistics students, 62 people were randomly as-signed to listen to rap music, music by Mozart, or no music while attempting to memorize objects pictured ona page. They were then asked to list all the objects theycould remember. Here are summary statistics: a) Does it appear that it is better to study while listeningto Mozart than to rap music? Test an appropriatehypothesis and state your conclusion. b) Create a 90% confidence interval for the mean differ-ence in memory score between students who study to Mozart and those who listen to no music at all.Interpret your interval. Rap Mozart No MusicCount 29 20 13Mean 10.72 10.00 12.77SD 3.99 3.19 4.73
A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6 Mean: 12.7 Mean: 13 Since the simulation shows ( many cases or free cases )? where a mean difference of ( solve for this answer ) or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely ) ?due to the random assignment of participants into groups, so the results of the study are (…
