Scenario: A researcher wants to see whether ESP abilities in psychics differ based on environment. Thus, the researcher has psychics predict card suits in both a fortune-telling environment (e.g., low lighting, candles, a crystal ball), and in a standard lab environment. They complete 100 trials of the task in each environment, with the environment type counterbalanced between participants. All 30 psychics completed the card prediction task in both environments. Accuracy rates are compared. Question: Which of the following best describes the scenario? Between-subjects Within-subjects Mixed design

A random survey of 150 CBC students found that 35 of them intended to transfer to WSU Tri-Cities upon completing their AA degree. Construct a 95% confidence interval for the proportion of CBC students intending to transfer to WSU Tri-Cities. Give your answer as a complete sentence in the context of the problem.

A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned.   Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.”    Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations.   1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
