Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?

Q. 1In the population, the average score on a test of self-esteem is 50 (σ= 5). You select a randomsample of 25 students who score a mean of 53.a. Shine claims that these students don’t have very high self-esteem, because they are only 3points above the population mean. Why can’t she make this claim merely by looking atthe X? .b. What should she do? .c. What is the z-score for this sample? .d. What conclusion do you draw about your sample? .

I need help with a stat problem, section 7.2 and 7.3, thank you (please help with TI-84 commands) You receive a brochure from a large university. The brochure indicates that the mean class size for full-time faculty is fewer than 32 students. You want to test this claim. You randomly select 18 classes taught by full-time faculty and determine the class size of each. The results are shown in the table below. At α=0.10, can you support the university's claim? Complete parts (a) through (d) below. Assume the population is normally distributed. 38 29 29 31 30 41 25 23 30 27 31 33 36 31 29 32 27 23 (a) write the claim mathematically and identify Ho and Ha.
