the college bookstore says that the average cost of textbooks is $52 with a standard deviation of $4.50. a group of skeptical statistics students want to test the bookstore’s claim with a sample of 100 books, and find a mean of $53. a) what decision should the students make if they set alpha to .01?

b.) Compare and contrast the benefits and drawbacks of having a high alpha level vs. a low alpha level. What are some of the practical/real world implications of either setting an alpha level too high (i.e., .1) or too low (i.e., .001) in your study/analysis?

The college bookstore tells prospective students that the average cost of its textbooks is $52 with a σ of $4.50. A group of smart statistics students think that the average cost is much higher. In order to test the bookstore’s claim against their alternative, the students select a random sample of size 100. Assume that the mean from their random sample is $52.80. Use alpha value of 0.05 level to test the hypothesis.

The college bookstore tells prospective students that the average cost of its textbooks is $108 with a standard deviation of $4.50. A group of smart statistics students thinks that the average cost is higher. In order to test the bookstore’s claim against their alternative, the students will select a random sample of size 100. Assume that the mean from their random sample is $112.80. Perform a hypothesis test (using R) at the 5% level of significance and state your decision....

Amasoon is a bookstore selling economic textbooks, and Booky is a bookstore selling mathematics textbooks. While Amasoon owns a physical shop located in Denver, Booky operates on the internet. Therefore, Amasoon has a fixed cost of $180,000 per year, while Booky has no fixed cost. Since Amasoon has a physical shop, the publisher is willing to sell the textbooks to Amasoon at a discounted price of $60 per copy. Booky has to buy the books for $100 per copy from...
