    1. You want to test whether you can reject the null hypothesis that a population mean is greater than or equal to 10. To do this, you collect a random sample of size 500 from the population, and you calculate that the sample mean and sample standard deviation are 8.6 and s, respectively. Which of the following is true? a. If s is any value between 11 and 13, you can reject the null hypothesis at the 5% significance level....

    You read that a statistical test at the α=0.01 level has probability 0.14 of making a Type II error when a specific alternative is true. What is the power of the test against this alternative? Suppose we tested the null hypothesis that the weight of a McDonald's quarter pounder is 0.25 pounds (H0 : µ = 0.25) against the alternative that the weight is below 0.25 pounds (Ha : µ < 0.25). After collecting a sample our observed z statistic...
