Assume that we want to construct a confidence interval. Do one of the​ following, as​ appropriate: (a) find the critical value t
Feliz [49]

Considering that we have the standard deviation for the sample, the t-distribution will be used, and the critical value is t = 2.6682.

<h3>When should the t-distribution and the z-distribution be used?</h3>
  • If we have the standard deviation for the sample, the t-distribution should be used.
  • If we have the standard deviation for the population, the z-distribution should be used.

In this problem, σ is not​ known, hence we get the standard deviation of the sample from the histogram and the t-distribution is used.

Using a t-distribution calculator, considering a <em>confidence level of 99​%</em> and 56 - 1 = <em>55 df</em>, the critical value is t = 2.6682.
