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...

A researcher conducts a hypothesis test to evaluate the effect of a treatment. The hypothesis test produces a z-score of z = -2.60. Assuming that the researcher is using a two-tailed test, what is the correct statistical decision? Reject the null hypothesis with α = .05 but not with α = .01. Reject the null hypothesis with either α = .05 or α = .01. Fail to reject the null hypothesis with either α = .05 or α = .01....
