Basketball players can take shots worth 333 points, 222 points, or 111 point. A scout is assessing two players—Tabitha and Lauren—who play for different teams in different leagues. The scout wonders if they have similar or different shot selections. They take a random sample of Tabitha's games and a separate random sample of Lauren's games. They tally how many of each type of shot the players attempted in those games. Here is a summary and the results of a chi-square test: Chi-square test: Shot vs. player Tabitha Lauren 333-point 888 121212 Expected 10.3410.3410, point, 34 9.669.669, point, 66 222-point 404040 373737 Expected 39.8339.8339, point, 83 37.1737.1737, point, 17 111-point 121212 777 Expected 9.839.839, point, 83 9.179.179, point, 17 �2=2.097, DF=2, P-value=0.350χ2=2.097, DF=2, P-value=0.350\chi, squared, equals, 2, point, 097, comma, start text, space, D, F, end text, equals, 2, comma, start text, space, P, negative, v, a, l, u, e, end text,…
Please give correct Answers and Answer both parts. A B 6.13 Taste test. Some people report that just one sip, they can detect the difference between a diet and a regular Coke. A researcher wanted to test this claim, so he chose 80 persons at random. He then filled 80 simple white cups with soda, half diet and half regular, and asked each person to take one taste from their cup and identify the soda as diet or regular based on a random assignment. The drink was accurately identified by 53 of the participants. (a) Do these data show that these folks are any better or worse at telling the difference between diet and regular soda than random guessing? (b) Explain the significance of the p-value in this context.

Shenise is a star player for her women's basketball team. She has injured her ankle, and it is doubtful that she will be able to play in an upcoming game. If Shenise can play, the coach estimates that the team will score 91 points. If Shenise is not able to play, the coach estimates that they will score 70 points. The team doctor estimates that there is a 70% chance Shenise will play. Determine the number of points the team can expect to score.

A consumer group wanted to determine if there was a difference in customer perceptions about prices for a specific type of toy depending on where the toy was purchased. In the local area there are three main retailers: W-Mart, Tag, and URToy. For each retailer, the consumer group randomly selected 5 customers, and asked them to rate how expensive they thought the toy was on a 1-to-10 scale (1= not expensive, to 10 = very expensive). The toy was priced the same at all retail stores. 1. What kind of statistical test should be used to test the consumer group's research goal, assuming that the researcher wanted to use the 1-to-10 scale as a numerical interval measure? A. Repeated-measures t-test B. One-way Independent Measures ANOVA C. Repeated-measures ANOVA D. Independent-measures t-test 2. State the hypothesis that aims to test the consumer group’s research goal (i.e., what is H0 and HA).
