Based on a sample of n = 20, the least-squares method was used to develop the following prediction line: Ŷi = 5 + 3Xi. In addition,
a. Construct a 95% confidence interval estimate of the population mean response for X = 4.
b. Construct a 95% prediction interval of an individual response for X = 4.
c. Compare the results of (a) and (b) with those of problem (a) and (b). Which intervals are wider? Why?
Problem
Based on a sample of n = 20, the least-squares method was used to develop the following prediction line: Ŷi = 5 + 3Xi. In addition,
a. Construct a 95% confidence interval estimate of the population mean response for X = 2.
b. Construct a 95% prediction interval of an individual response for X = 2.
