The Regression Printout Below Shows the Results of a Regression

question 46

Multiple Choice

The regression printout below shows the results of a regression analysis intended to link variable x to variable y.A sample of 25 data points was used. Can you use the sample results shown here to reject a β = 0 null hypothesis at the 1% significance level? Explain.

• A)Yes, since the upper bound on the 95% interval estimate of β is greater than 0, we can reject the β = 0 null hypothesis.
• B)No, since the p-value for the intercept term is greater than the significance level of .01, we can't reject the β = 0 null hypothesis.
• C)No, since the p-value for the coefficient of the x variable is greater than .01, we can't reject the β = 0 null hypothesis.
• D)No, since t_stat for the x variable is inside ±2.069, we can't reject the β = 0 null hypothesis.
