Due on Thursday, April 3, 1997

Read Chapter 16 and Sections 17.1-2.

Do the following exercises in the text:

16.14: For the data set in Exercise 15.38 , test if there are differences in waiting times among three resorts. Justify the assumptions used in your test(s).

16.15: Book Bindings Data

16.17: Survey Data

17.6

17.8

Additional Problem A random sample of n=100 observations were selected in order to test the following hypothesis using the goodness of fit test.

Ho: p1= (theta1)^2 + 2 (theta1)(theta2), p2= (theta2)^2 + 2 (theta2)(theta3), p3= 2 (theta1)(theta2), p4= (theta3)^2

such that theta1+theta2+theta3=1.

If we use the chi-square goodness of fit test to test this null hypothesis, what are degrees of freedom associated with this test?
