True or False: Underreporting in surveillance programs makes diseases appear less prevalent than they actually are.

Using the data in the table from a study assessing the link between asthma and the risk of developing obstructive sleep apnea (OSA), calculate the cumulative incidence of OSA among study participants without asthma assuming no participants dropout over the course of the study.

True or False: During the initial examination for an epidemiological study, existing cases of coronary heart disease were identified in 5 per 1,000 men and 2 per 1,000 women. From this data, it would be reasonable to deduce that men have a higher risk of developing coronary artery disease than women.

Let X be the number of taxis that a customer finds waiting outside of their hotel anytime between 5:00pm and midnight on weeknights. The probability mass function for X is Solve for the following probabilities. Round to the nearest hundredth. d)

The next two questions use the same problem statement.  An industrial psychologist has developed a test to identify people with a potential to be good managers. His statistics indicate that 30 percent of the employees in the company positive leadership traits. Past data indicates that 45 percent of those with positive traits are promoted into management, while 10 percent of those without the traits are promoted into management. a) What is the probability that an employee picked at random from the company will be promoted to management? Round to the nearest thousandth.
