Answer to Question 1

ANS: A
Analysis of variance is used to test for difference between means and can examine data from two or more groups simultaneously.
Chi-square determines whether two variables are independent or related.
t-tests should not be used for multiple groups simultaneously.
t-tests should not be used for multiple groups simultaneously.

ANS: D
The t-test is used to determine if there is a significant difference between groups with data measured at the interval or ratio level.
There are several measures of central tendency; none of them would be used to find a significant difference between groups.
Chi-square determines whether two variables are independent or related.
Pearson product moment correlation is a parametric test used to determine relationships among variables.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).
