Answers

If Morris wanted to construct a one-sample t-statistic, what would the value for the degrees of freedom be 9.

What is t-statistics?

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-

T-tests are performed when the data sets get a normal distribution with unknown variances, such as when a coin is flipped 100 times.

The t-test is a statistical hypothesis test that uses the t-statistic, t-distribution values, and degrees of freedom to evaluate statistical significance.

A t-test is a statistical test used to test hypotheses.

The t-test requires three essential data values: the difference in mean values between data sets, a standard deviation of every group, or the number of data items.

T-tests can be either dependent or independent in nature.

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.
