Question

Find the critical value needed to construct a confidence interval of the given level with the given sample size. Round the answer to at least three decimal places. Level 95%, sample size 10.

Answer 1

Using the t-distribution, the critical value needed is: t = 2.2622.

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

The critical value is found using a calculator, with two parameters:

• The confidence level.

• 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.
