Using the t-distribution, the critical value needed is: t = 2.2622.
<h3>How to find the critical value for the t-distribution?</h3>
The critical value is found using a calculator, with two parameters:
- The number of degrees of freedom, which is one less than the sample size.
For this problem, we have a confidence level of 95% and 10 - 1 = 9 df, hence the critical value is t = 2.2622.
