Question

Find the critical value Tc for the confidence level c=0.80 and sample size n=29

Answer 1

Using a calculator, the critical value for the t-distribution with a confidence level c=0.80 and sample size n=29 is of Tc = 1.3125.

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

It is found using a calculator, with two inputs, which are given by:

• The confidence level.

• The number of degrees of freedom, which is one less than the sample size.

In this problem, the inputs are given as follows:

• Confidence level of 80%.

• 28 degrees of freedom, as there is a sample size of 29.

Hence, using a calculator, the critical value for the t-distribution with a confidence level c=0.80 and sample size n=29 is of Tc = 1.3125.
