QuestionYour answer is partially correct.
Is a t-Distribution Appropriate? A sample with size $n=12$ has $\bar{x}=7.6$ and $s=1.6$. The dotplot for this sample is given below.
Indicate whether or not it is appropriate to use the $t$-distribution.
Yes $\leqslant$
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. $d f=$ i $\square$ standard error = $\square$ eTextbook and Media Hint Attempts: 1 of 5 used Submit Answer
