Question

If the t ratio for the slope of a simple linear regression equation is equal to 3.614 with a p-value of 0.006, then the slope is

Answer 1

Then the slope is Significantly different from zero at both the 5% level and the 1% level.

Explanation:

In statistics for a value to be said to be significant, this value has to be less than p value at the selected level of significance.

Here,

P value = 0.006

5% significance level = 0.05

0.006 < 0.05, so the slope value is significant at 5% significance level.

1% significance =0.001

0.006 is less than 0.01 so the slope coefficient is also significant at 1% significance level
