Is a t-Distribution Appropriate?

A sample with size n=12 has x¯=7.6 and s=1.6. The dotplot for this sample is given below.

Indicate whether or not it is appropriate to use the t-distribution.

If it is appropriate, give the degrees of freedom for the t-distribution and give the estimated standard error. If it is not appropriate, enter -1 in both of the answer fields below.

Enter the exact answer for the degrees of freedom and round your answer for the standard error to two decimal places.

d⁢f=

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
