(g) Based on the estimated equation in part (a), calculate the estimated PIQ score for a male student with MRI total pixel count equal to 1001121. Moreover, obtain a 95% confidence interval and a 95% prediction interval for the estimated PIQ score for a male student with MRI total pixel count equal to 1001121. Which of the two intervals is wider? Given the plots obtained in parts (e) and (f). which interval is more trustworthy
