Which one of the following statements is true using alpha = 0.05
a. Because the p -value for the slope is 0.0423, we can reject the null hypothesis and conclude that there is a relationship between the weekly rental and square footage of beach property.
b. Becsuse the p -value for the slope is 0.0423, we fail to reject the null hypothesis and conclude that there is a relationship between the weekly rental and square footage of beach property.
c. Because the p-value for the slope is 0.0870, we can reject the null hypothesis and conclude that there is a relationship between the weekly rental and square footage of beach property.
d. Because the p -value for the slope is 0.0870, we fail to reject the null hypothesis and conclude that there is a relationship between the weekly rental and square footage of beach property.
