If Morris wanted to construct a one-sample t-statistic, what would the value for the degrees of freedom be 9.
The t-test would be an inferential statistic that is used to assess whether or not there is a significant variation between the averages for two groups & how they are related.
Some key features of t-test statistics are-
Now, according to the question;
The degrees of freedom of first sample t-test are df=n-1
where n is the sample size.
So, n=10, then df = n-1 = 10-1 = 9.
Therefore, the degree of freedom for the t-test is 9.
