1.What is the relationship between the power of a test and the types of errors you can make?
Answer :
The power of a test is equal to 1 minus the probability of a Type Il error.
2.The National Collegiate Athletic Association (NCAA) requires colleges to report the graduation rates of their athletes. Here are data from a Big Ten university's report: 45 of the 74 athletes admitted in a specí fic year graduated within 6 years. Does the proportion of athletes who graduate di ffer signi ficantly from the all-university proportion, which is .70? What is the sample proportion?
Answer :
From provide information
n = 74 ,x = 45
Therefore sample proportion = x / n = 0.61

Use this information to answer the next four questions The National Collegiate Athletic Association (NCAA) requires colleges to report the graduation rates of their athletes. At one large university, 78% of all students who entered in 2010 graduated within six years. In a random sample of 190 student athletes in this university, 137 graduated within six years. Is there sufficient evidence to believe that the proportion of athletes who graduate within six years is less than 78%? Use α-.05. 34....

Which of the following statements is FALSE? a.) The power of a hypothesis test is the probability of not making a Type II error. b.) Alpha (α) is equal to the probability of making a Type I error. c.) The probability of rejecting the null hypothesis when the null hypothesis is true is called a Type I Error. d.) A smaller sample size would increase the effectiveness of a hypothesis test.

Suppose that we wish to test the null hypothesis Ho that the proportion p of ledger sheets with errors is equal to .05 versus the alternative Ha , that the proportion is larger than .05, by using the following scheme. Two ledger sheets are selected at random. If both are error free, we reject Ho. If one or more contains an error, we look at a third sheet. If the third sheet is error free, we reject Ho. In all...
