An Experiment Was Performed on a Certain Metal to Determine

Multiple Choice

An experiment was performed on a certain metal to determine if the strength is a function of heating time.Partial results based on a sample of 10 metal sheets are given below.The simple linear regression equation is = 1 + 1X .The time is in minutes and the strength is measured in pounds per square inch,MSE = 0.5, = 30, = 104. Determine the 95% prediction interval for the strength of a metal sheet when the average heating time is 2.5 minutes.

A) (1.68 5.32)
B) (2.94 4.06)
C) (1.78 5.22)
D) (0.78 4.22)
