Pick the test: (z test, correlation, independent sample t test, single sample t test, ANOVA, paired sample t test, or dependent sample t test) 1. A social psychologist wishes to compare men and women with respect to their attitudes toward abortion. She selects two independent samples and compares their responses. 2. Entrance to, and exit from, a large departmental store is via one of two doors. The number of customers entering or leaving the store is counted at each of the doors for a period of time. It is claimed that the numbers of customers using each of the two doors is the same. Investigate the claim. 3. A sleep researcher wanted to see if there are differences in the alertness level (as measured by the time to complete a word search) of people 10 minutes after waking depending on the method of waking them up. One group of people was awoken with a gradual increase in light levels in their bedrooms, and another group was awoken by a noisy alarm clock. 4. A psychologist records the time it takes 10 rats to make their way through a maze to a reward. The rats are then given a drug; the experiment is repeated and the time to run the maze to the reward is recorded again. He wants to know if the drug affects the time to run the maze. 5. Professor Smith is interested in whether males and females differ in their performance in a statistics course. If he assesses how the 23 males and 31 females in her statistics course perform on the course final exam, what is the appropriate statistical analysis to determine whether males and females differ?
