Question

. Dr. Hafen is doing research on the effects of study time (how many minutes students study) on test performance (their score on an exam).  He hypothesizes that the amount of study time will impact an individual’s performance on the exam.  Then Dr. Hafen collects data on 100 students.  He collects data on their ‘study time’ and their ‘exam performance’, then runs a Pearson correlation

In your own words, please describe what Dr. Hafen’s null hypothesis would be and what Dr. Hafen’s alternative hypothesis would be.  If Dr. Hafen makes a Type I error, what would that mean in the context of this study?  If he makes a Type II error, what would that mean in the context of this study?
