You are given the following summary statistics from a regression analysis:

yn = 200 + 150x SSE = 25.25 SSX = Sum of square X = (x - x)2 = 99,645 n = 18 x = 52.0

a. Determine the point estimate for y if xp = 48 is used.

b. Provide a 95% confidence interval estimate for the average y, given xp = 48. Interpret this interval.

c. Provide a 95% prediction interval estimate for a particular y, given xp = 48. Interpret.

d. Discuss the difference between the estimates provided in parts b and c.
