An Experiment Was Performed on a Certain Metal to Determine

question 62

Short Answer

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 ŷ = 1 + 1X. The time is in minutes, the strength is measured in pounds per square inch, MSE = .5, Σx = 30, and Σx² = 104. Determine the 95 percent prediction interval for the strength of a metal sheet when the average heating time is 2.5 minutes.
