Researchers at an infectious disease clinic interested in investigating the relationship between mortality and a number of comorbidities in their patients that are HIV positive. Researchers hypothesize that early mortality is most strongly associated with heroin use in their patient population. In order to better assess their relationship, the researchers decided to control for a variety of other comorbidities along with age and gender. The following is a representation of their multiple linear regression model (NOTE: the output is a bit...

6.48 Coffee and Depression. Researchers conducted a study investigating the relationship between caffeinated coffee consumption and risk of depression in women. They collected data on 50,739 women free of depression symptoms at the start of the study in the year 1996, and these women were followed through 2006. The researchers used questionnaires to collect data on caffeinated coffee consumption, asked each individual about physician-diagnosed depression, and also asked about the use of antidepressants. The table below shows the distribution of...

Researchers interested in determining if there is a relationship between anxiety and religiosity conducted the following study. Subjects completed a 5 point anxiety item (high score = high anxiety) and also completed a 15 item checklist designed to measure an individual’s degree of religiosity (belief in a particular religion, regular attendance at religious services, etc). A high score indicates greater religiosity. Sample data from 10 subjects are provided below. Can you predict anxiety (y) from religiosity (x)? First determine the...

In a study investigating the difference in food preferences between men and women, researchers asked subjects to indicate whether they like or disliked certain foods. One question was about lamb. Twenty percent of a sample of 75 men disliked lamb, while 38% of a sample of 100 women indicated that they disliked lamb. Test the claim that there is a difference in the proportions of men and women who dislike lamb. Indicate the correct set of statistical hypotheses for this...
