Use the following to answer the questions below:
Computer output from a regression analysis is provided.
The regression equation is Y = 72.9 - 0.519 X

-Use the p-value for testing if the slope in the population is different from zero (and a 5% significance level) to make a clear conclusion about the effectiveness of the model.
A) p-value = 0.008 There is very strong evidence that the population slope differs from zero, and thus is an effective model for predicting this response variable.
B) p-value = 0.008 There is not enough evidence that the population slope differs from zero, and thus this is not an effective model for predicting this response variable.

Since the p-value (0.008) is less than the significance level (0.05), there is strong evidence to reject the null hypothesis, indicating that the slope is significantly different from zero, making the model effective.
