An experiment was performed on a certain metal to determine if the strength is a function of heating time. The simple linear regression equation is ŷ = 1 + 1X. The time is in minutes and the strength is measured in pounds per square inch. The 95 percent confidence interval for the slope is from .564 to 1.436. Can we reject β1 = 0?
