Question

thirty - seven different video games showing violence were observed. the duration times of violence (in seconds) were recorded. when using this sample for a t test of the claim that the population mean is greater than 89 sec, what does df denote, and what is its value? what does df denote? a. the test statistic b. the sample standard deviation c. the number of degrees of freedom d. the sample size

Explanation:

In a t - test, df is a common notation. The degrees of freedom for a one - sample t - test is calculated as \(n - 1\), where \(n\) is the sample size. Here, the sample size \(n=37\).

Answer:

C. The number of degrees of freedom.
The value of \(df=n - 1=37-1 = 36\).
