Question
Chapter 9, Problem 13PIAT
Summary Introduction
To review:
From the given graph and study, the investigators determined that a low concentration of DNP increased the average life span from 719 days (Control) to 770 days (DNP). If the U.S. population has an average life span of 79 years, then how many years would be added if the same percentage increase were observed.
Introduction:
The 2,4-dinitrophenol (DNP) is used for the mice for reducing the production of reactive oxygen species (ROS), which allows the free passage of the protons across the inner mitochondrial membrane. The rate of survival is increased in the DNP treated mice as the oxidative damage caused by the ROS is decreased by the drug. The effect of a drug called DNP on the life span of mice is shown in the graph below. Each point represents the death of a single mouse.

A cohort of 3,400 people followed for 10 years, of whom 1,600 were exposed to a chemical and another 1,800 who were not exposed. As the outcome, the incidence of cases of myeloid leukemia was measured. In the exposed group there were 100 cases and in the group without product exposure (25) cases in 10 years (prospective cohort study).
a. Prepare a contingency table b. Compute and interpret the following: b.1 Cumulative incidence b.2 CI exposed and unexposed b.3 Relative risk b.4 Attributable risk b.5 Attributable risk among the exposed
Compare the 95% confidence interval for the difference between two true means with the 95% confidence interval for an individual true kean. Describe one way in which these two equations are similar and state four ways in which these equations differ.
