Answer:

Correct option: b 39.

Step-by-step explanation:

A one-sample (or one mean) t-test is applied to test whether the population-parameter is significantly different from some hypothetical value.

The degrees of freedom of the <em>t</em>-test is:

df = n - 1

It is provided that the sample size is, <em>n</em> = 40.

Compute the degrees of freedom as follows:

df = n - 1

= 40 - 1

= 39

Thus, the correct option is b.
