Is a t-Distribution Appropriate? A sample with size n=75 has x¯=18.92, and s=10.1. 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. df= standard error =
