You are planning to evaluate the mean of a single continuous variable from a study with a sample of n =10 using the t statistic. What are the degrees of freedom for the sample? a. 11
b. 9
c. 10
d. 8

And for this case the degrees of freedom are given by:

And the best option would be:

b. 9

Step-by-step explanation:

For this case our parameter of interest is the true mean and we have a sampel size of n =10.

We are going to use a t test and then the t statistic given by:

And for this case the degrees of freedom are given by:

And the best option would be:

b. 9

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
