Question

Question 4 (1 point) A study was conducted to determine if males residing in the U.S. who smoke are more prone to dementia than those who do not smoke. Over a span of 8 years, the study attracted 8670 male volunteers in the cities of Dallas and Houston who were between the ages of 40 and 50 when they started the study. Twenty five years later it was determined that 1890 had some form of dementia. From these results it was determined that males who smoked at least one pack a day were 39% more likely to get dementia than those who did not smoke.
