Problem 2E

Suppose that a third group of nurses was observed along with groups I and II of Exercise 9.2-1, resulting in the respective frequencies 130, 75, 136, 33, 61, and 65. Test H0: pi1 = pi2 = pi3, i = 1, 2, . . . , 6, at the α = 0.025 significance level.

References Exercise 9.2-1

We wish to see if two groups of nurses distribute their time in six different categories about the same way. That is, the hypothesis under consideration is H0: pi1 = pi2, i = 1, 2, . . . , 6. To test this hypothesis, nurses are observed at random throughout several days, each observation resulting in a mark in one of the six categories. A summary of the results is given by the following frequency table:

Use a chi-square test with α = 0.05.
