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,the strength is measured in pounds per square inch,MSE = 0.5,
= 30,and
= 104.Determine the 95 percent confidence interval for the average strength of a metal sheet when the average heating time is 2.5 minutes.
