Based on the data from six students the regression equation

Based on the data from six students, the regression equation relating the number of hours of preparations (x) and test score (y) is.The same data yield an r = 0.224 and a What is the best predicted test score for a student who spent 3 hours preparing for the test? Think before acting on this problem. Include the null hypothesis, the alternative hypothesis, the calculation of the experimental r-value, the decision rule and the conclusion drawn.
