Statistics 13C Homework # 5For discussion, Tues, 10/28/08F. J. SamaniegoFrom the text: Chap. 7: Problems (dealing with μ) # 25, 33, 63. All the following problems deal with confidence intervals for a population mean μ. Chap. 8: Problems # 23, 27, 28, 29, 31, 37. Chap. 10: Problems: # 1, 8, 11. Also, solve the following problems: 1. Let X be the number of servings that a randomly chosen meal card holder will have for dinner at Segundo Dining Commons. The manager at Segundo has noticed that X has the distributionX0123P(X)1/61/61/61/2Approximate the probability that 96 random meal card holders will consume at least 200 servings, that is, approximate P(X≥ 2.0833). (Hint: Evaluate μ & σ2 for the distribution above and apply the Central Limit Theorem to X.)2. The national mean score on the SAT test (including verbal, quantitative and written parts) seems to vary from year to year, so that last year’s mean score is not a reliable predictor of this year’s mean score. Anyway, these means would be inapplicable to students at Carnegie High in Pittsburgh, a
