Question 2

The makers of furnace filters recently conducted a test to determine whether the median number of particulates that would pass through their four leading filters was the same.

A random sample of 6 of each type of filter was used with the following data being recorded:

Filter 1 Filter 2 Filter 3 Filter 4
40 100 165 55
25 110 90 20
70 89 40 90
47 67 200 105
55 77 103 90
88 102 110 120

The Kruskal-Wallis test can be used in this case since it requires that the sample sizes be equal.
