Q3) An educational researcher have seen that some high school students who miss a lot of school days seemed to also have lower GPAs. He is interested in examining these two variables, number of days absent and GPA, to see if what he has seen in casual observation (higher absence rate is related to lower GPAs) might be a true phenomenon. He sets the alpha level at a= .05 for a one-tailed test. (3 points total)
