Would greatly appreciate some help on this question. Thanks!

2. Consider the following summary statistics of study times X and exam scores ) for a sample of n = 52 students. 7 hours Sx 2 hours 73% Sy 14% 40 r 0.3 a. (+3) Using these summary statistics, estimate the slope and intercept parameters of a linear regression of exam scores on study times, and predict the exam score of a student who studies for exactly ten hours. b. (+1) Use the equation Ser = (1 - r?)Syy to derive an estimate s, of the standard deviation of errors off the regression line. c. (+6) Use your answer to part b to find 95% confidence intervals for the three point estimates reported in part a
