A sample with size has , and . The dotplot for this sample is given below. A dotplot ranging from 58 to 95 with dots plotted as follows: 1 dot above 58, 1 dot above 68, 1 dot above 77, 1 dot above 81, 2 dots above 86, 1 dot above 90, 2 dots above 93, 5 dots above 94, and 4 dots above 95. Indicate whether or not it is appropriate to use the t-distribution. Choose the answer from the menu; 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 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.
