Consider the following partially completed computer printout for a regression analysis where the dependent variable is the price of a personal computer and the independent variable is the size of the hard drive. Based on the information provided,which of the following statements is true if alpha = .05?
A)The slope is not significantly different from 0 because p = 0.84 is greater than 0.05.
B)The slope is significantly different from 0 because p = 9.95 is greater than 0.05.
C)The slope is not significantly different from 0 because p = 9.95 is greater than 0.05.
D)The slope is significantly different from 0 because p = 9.95E-10 is less than 0.05.

The p-value provided for the slope is 9.95E-10, which is much less than the significance level of 0.05. Therefore, we reject the null hypothesis that the slope is zero and conclude that there is a significant relationship between the size of the hard drive and the price of a personal computer.
