You complete a hypothesis test using alpha = .05 and based on the evidence from the sample, your decision is to fail to reject the null hypothesis. If the treatment actually does have an effect, which of the following is true?

Also, using α = .05, run a two-tail t-test for one sample to test Ho: µ=283 for the 2009 scores. Report the t-obt, df, and p-values. Would you reject the null hypothesis that the 2009 scores come from a population with average 283? If this is the case, does it come from a population from larger or smaller average?

What statistical test would you use for each of the following scenarios? What would you set your alpha-level at? Sarah wants to know how gender impacts heart rate recovery after a maximal exercise test. In order to test this, she has both male and female athletes come into her lab and she measures both resting heart rate before the exercise test and heart rate immediately, 10 minutes, 20 minutes and 30 minutes following the exercise test. In order for her to determine whether heart rate differs pre-post exercise between males and females what statistical test might she use? Why?
