Textbook Question

Chapter 7, Problem 14P

Suppose the incidence rate of myocardial infarction (Ml) was 5 per 1000 among 45- to 54-year-old men in 2000. To look at changes in incidence over time, 5000 men in this age group were followed for 1 year starting in 2010. Fifteen new cases of Ml were found.

Of the 15 new Ml cases in the preceding study, 5 died within 24 hours. Test whether the 24-hour case- fatality rate changed from 2000 to 2010.
