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 = 1 + 1X.The time is in minutes and the strength is measured in pounds per square inch. The 95% confidence interval for the slope is from .564 to 1.436.Can we reject $\beta$₁ = 0? A)Reject H₀ B)Fail to reject H₀

Question

Quizplus · Accepted Answer

Since the 95% confidence interval for the slope does not include zero (the null hypothesis), we can reject the null hypothesis at the 0.05 level of significance. Therefore, we can conclude that the strength of the metal is significantly related to heating time.
