In this section, we illustrated the Kruskal-
Wallis test with data on miles driven by samples of cars, buses, and trucks. The value of the test statistic K was computed on page 729 to be 9.930, whereas on page 731, we found its value to be 9.923.
a. Explain the discrepancy between the two values of K.
b. Does the difference in the values affect our conclusion in the hypothesis test we conducted? Explain your answer.
c. Does the difference in the values affect our estimate of the P-value of the hypothesis test? Explain your answer.
