Question 135

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 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% confidence interval for the average strength of a metal sheet when the average heating time is 2.5 minutes. A) (2.94 4.06) B) (1.78 5.22) C) (3.31 3.69) D) (1.94 3.06) = 1 + 1X .The time is in minutes and the strength is measured in pounds per square inch,MSE = 0.5, 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.
