Your answer is partially correct. Is a t-Distribution Appropriate? Asample with size n = 18 has x = 87.9, and s = 10.6. The dotplot for this sample is given below. 90000 60 70 80 90 100 Indicate whether or not it is appropriate to use the t-distribution. No 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 - I 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. df = i standard error = 1 eTextbook and Media Assistance Used Hint Assistance Used The t-distribution is appropriate if the sample size is large (n 2 30) or if the underlying distribution appears to be relatively normal.
