This is the step 1. 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. Based it from the photo You may answer step 2 and step 3 which is “ Step 2: Test Statistic -Pearson's r correlation coefficient Step 3: Critical Values”
