Mathematics

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?

Okay i know this is kinda a lot but i really dont understand these can someone me when you multiply a number by a percent, you find the sum. true false geoff estimates that 27% of 121 is about 30. which of the following statements is true? his estimate is way too high. his estimate is way too low. his estimate is good. there is not enough information. which of the following is the best estimate for 77% of 60? 15 30 45 60 ; )

Step-by-step answer

1. The answer to addition problems is referred to as the sum, multiplication as the product, subtraction as the difference and division as the quotient. So...False.
2. You could turn the percent into a decimal, after rounding to 25, and multiply it by 121 to get about 30. However, I find it easier to just move the decimal one place to the left and multiply the product by how many tens are in the estimated percent.
10% = .10 .10 x 121 = 12.1 x 3 = 36.3 Which is still rather close and doesn't need a calculator.
3. Using the methods earlier, I'd say the best estimate is 45.
