Use the following to answer the questions below:

Computer output from a regression analysis is provided.

 Coefficients: Estimate Std. Error t value Pr(>|t|) (Intercept) 7.2960 14.5444 0.502 0.62200 X 1.6370 0.5453 3.002 0.00765

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.

▸ p-value = 0.00765

There is not enough evidence that the population slope differs from zero, and thus is not an effective model for predicting this response variable.

▸ p-value = 0.00765

There is very strong evidence that the population slope differs from zero, and thus is an effective model for predicting this response variable.
