Activity 2: Jonna is a good student, but at times she doesn't get enough sleep. She hypothesizes that when she gets more sleep she does better on tests. To test her hypothesis, she tracked how she did on a number of tests, based on how many hours of sleep she got on the night previous. She inputs the following data into her excel file to compute the correlation coefficient equation. Is there a significant correlation between the hours of sleep and test scores?
