-Pearson's r correlation coefficient AND Step 3: Critical Values ) so based it from the photo. Show COMPLETE SOLUTIONS. The table shows the number of hours spend by 30 students in studing and their test scores. Solve for the Pearson’s r and interpret the results. Use 5% significance level.
Step 1: Null and Alternative Hypothesis
Ho: r = 0; There is no significant relationship between the number of hours spent studying and the students test scores.
Ha: r ≠ 0; There is a significant relationship between the number of hours spent studying and the students test scores.
