And the coefficient that The constant coefficient studying in a given week. in the experiment, the variable that is not dependent on any other factors of the experiment is the amount of caffeine being consumed (hence it is the independent variable). Therefore, the confidence interval is b2 +/- t SE (b). And to do that we need to know We reject $H_0$ at $5\%$ level of significance if $\text{observed } T>t_{0.05,n-2}$ where $t_{0.05,n-2}$ is the upper $5\%$ point of a $t$ distribution with $n-2$ degrees of freedom.
