For MWATU 1. Event A occurs with probability 0.2. Event B occurs with probability 0.8. If A and B are disjoint (mutually exclusive) then a) P(A and B) = 0.16. b) P(A or B) = 1.0. c) P(A and B) = 1.0. d) P(A or B) = 0.16. 2. A researcher states that the time it takes an adult to complete a certain paper and pencil maze is negatively associated with age. This means a) above average values of age tend to accompany above average values of time to complete the maze. b) below average values of age tend to accompany below average values of time to complete the maze. c) below average values of age can be accompanied by either above or below average values of time to complete the maze. d) above average values of age tend to accompany below average values of time to complete the maze.

The sample is a) all viewers listening to the show. c) the 1574 viewers who are opposed. b) the 2241 viewers who phoned in. d) the 667 viewers who are in favour. 4. The one-sample t statistic from a sample of n = 19 observations for the two-sided test of H0: µ = 6, Ha: µ ? 6 has the value t = 1.93. Based on this information a) we would reject the null hypothesis at ? = 0.10. b) 0.025 < P-value < 0.05. c) we would reject the null hypothesis at ? = 0.05. d) All of the above.
