Homework: Chapter 8 (Inference for proportions, chi-square tests)

Test of change in a proportion (Moore and McCabe section 8.2):
Problem 8.31 (effectiveness of aspirin in treatment of stroke)

Test of independence in two-way tables (Moore and McCabe section 8.3):

Problem 8.40 (Relationship between prescription practices and doctor location)
Problem 8.56 (Relationship between blood type and ethnic groups)
Problem 8.74 (Statistics in law -- fairness of jury selections)

Goodness of fit to a hypothesized distribution (from handout and notes on web):

A. Pseudo-random number generation: Use Minitab to generate 200 values supposed to have the uniform distribution with values between 0 and 1. Give a histogram of the observed counts with five or ten equal spaced bins. What would be the expected counts according to the uniform distribution? Conduct a chi-square test of goodness of fit.
B. Give a chi-square test of normality of the mathematics SAT scores in the Minitab data file ``GRADES.MTW''
