Question eUsing the 5% significance level, what is the decision and conclusion for the test? Do you reject or not reject the null hypothesis. Is there enough evidence or not enough evidence that NHL players eat more calories than NBA players, on average.

webwork.ucalgary.ca titian is interested in studying the mean daily caloric intake of professional hockey players. To collect data for her study, she enlists the participation of a random sample of 60 current National Hockey Leagu ers. She asks each athlete to keep a food diary over a month during their season, from which she determines a daily caloric intake value for each player. Remaining time: 15 m the sample of 60 NHL players, the dietitian obtains a sample mean of 4300 daily calories with a sample standard deviation of 780 calories. (Worth 10% for each) Construct a 95% confidence interval for the mean number of daily calories consumed by an NHL player. (Express by four decimal places) SHS Suppose the average caloric intake of professional basketball players in the National Basketball Association (NBA) is known to be 4060 calories from a previous survey. Conduct a hypothesis test at the 5% significance level to assess whether NHL players have higher average caloric intake than NBA players. (b) (Worth 20%) What are the null and alternative hypotheses for this test? OA. HO : X = 4060 Ha : x / 4060 OB. HO : x = 4060 Ha : T > 4060 C. Ho : H = 4060 Ha : H 4060 OF. HO : H = 4060 Ha : Ml # 4060 OG. Ho : M > 4060 Ha : p = 4060 H. Ho : T = 4060 Ha : x Test statistic) B. P(T59 > Test statistic) OC. P(T60 / Test statistic) D. P(T59 # Test statistic) E. P(T59
