An Experiment Was Performed on a Certain Metal to Determine

question 65

Short Answer

An experiment was performed on a certain metal to determine if its 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. Time is in minutes, strength is measured in pounds per square inch, MSE Σx = .5, Σx = 30, and Σx² = 104. The distance value has been found to be equal to .17143. Determine the 95 percent prediction interval for the strength of a metal sheet when the average heating time is 4 minutes.
