Question

A graphing calculator is recommended. Are the mean numbers of daily visitors to a ski resort the same for the three types of snow conditions? Suppose that the table below shows the results of a study. Powder Machine Made Hard Packed 1,211 2,106 2,846 1,081 1,148 1,637 1,537 861 2,020 940 1,870 1,177 1,528 2,234 1,381 Assume that all distributions are normal, the three population standard deviations are approximately the same, and the data were collected independently and randomly. Use a level of significance of 0.05.

a. What is the test statistic? (Round your answer to two decimal places.)
b. What is the p-value? (Round your answer to four decimal places.)

Can you show steps on how to do it on the calculator.
