Question

20. The logistic regression equation y -2.592 +0.415x1+ 0.655x2 can be used to describe the association between incident cardiovascular disease (y) and obesity status (x1, coded as 1-obese and 0-not obese), adjusting for age (xa). Based on the equation, we can know that, while adjusted for age, a non-obese people is actually more likely to have incident cardiovascular disease than an obese people is. 21. If a 90% confidence interval for the mean is (75.3, 80.9), there is 10% chance that the true mean is not within this range.

Explanation / Answer

20. Statement is False. Coefficient of x1 is positive, so obese people are more likely to get the disease.

21. Statement is False. 90% of such intervals would contain the true mean.
