# Testing the Regression Model II

Have a look at the output from your last question (enter `summary(mod1)`

into your console). The column "Estimate" shows the coefficients for the intercept (top) and the regression slope (bottom), "Std.Error" shows you the standard error, "t value" shows the t-value, and "Pr(>|t|)" shows you the p-value associated with the t-value.

Based on the p-value for the slope coefficient, which of the following statments is correct?

##### Possible Answers

- The slope coefficient is significantly different from zero, so we reject the null hypothesis.
- The slope coefficient is not significantly different from zero, so we reject the null hypothesis.
- The slope coefficient is significantly different from zero, so we accept the null hypothesis.
- The slope coefficient is significantly different from zero, so we accept the null hypothesis.
