Using a t-distribution calculator, it is found that the critical value for the hypothesis test is of t = 1.3277.

How to find the critical value of the t-distribution?

The critical value is found considering three inputs:

  • The tail.
  • The significance level.
  • The amount of degrees of freedom, which is one less than the sample size.
