On this case the test statistc is given by
And the p value obtined was: and since the p value is lower than th significance level we can reject the null hypothesis at 5% of significance. The slope is significant.
Step-by-step explanation:
We assume the following info:

And we can use excel to solve the problem
Part a
On this case we need to click on Data>Data analysis>Regression>Ok
We select the input Y range and th X range and then we click in Ok.
The output obtained is on the first figure attached.
And in order to estimate the regression line we need to look into the column Coefficients, and for this case we got:
And the linear model would be given by:
For the determination coefficient we have:
And the adjusted
And if we analyze the output th F statistic is given by:
Part b
We want to test:
H0:
H1:
On this case the test statistc is given by
And the p value obtined was: and since the p value is lower than th significance level we can reject the null hypothesis at 5% of significance. The slope is significant.
The standard error for the slope is given in the output:
We reject the null hypothesis.
