Regression: weekend vs school night

Predictor Coef SE Coef
Constant 3.182 2.319
School night 0.789 0.237
S= 1.75 R-Sq= 20.9%

Required:
What is an appropriate test statistic for testing the null hypothesis that the population slope in this setting is 000?

Answer 1

The answer is "3.329".

Step-by-step explanation:

Please find the complete question in the attached file.

$\text{test statistic t} = \frac{slope}{standard \ error}$

                      $=\frac{0.789}{0.237}\\\\=3.329$
