Data are collected for the scores y of n = 10 randomly selected students from a statistics class and the number of hours x they slept the night before the attempt. Summary statistics are x = 4.2, sx = 1.874, and se = 6.305; the least squares line is = 5.044x + 56.11. Construct a 95% prediction interval for the mean attempt score of a particular student that got x = 5 hours of sleep the night before the attempt (use 2 decimal places).

Suppose we have collected the midterm and final scores of 200
students in a Statistics class, and we observed that the scatter
plot of final scores versus midterm scores is roughly linear.
Suppose the average midterm score is 76, with SD 12, and the
average final score is 71, with SD 10. Suppose the correlation
coefficient between midterm and final scores is 0.6.
Use the regression line, or an equivalent regression procedure, to
predict the final score for someone who...
