Assessment examples from Chapter 1 Sample quiz #1 1. Which definition of a p-value is the most accurate? a. If the alternative hypothesis is true, the p-value is the probability of observing an outcome as extreme or more extreme than the one actually observed in the study b. The p-value is the probability that the alternative hypothesis is true c. If the null hypothesis is true, the p-value is the probability of observing an outcome as extreme or more extreme than the one actually observed in the study d. The p-value is the probability that the null hypothesis is true Circle TRUE or FALSE each of the following (#2 through #5) 2. A p-value can be negative TRUE FALSE 3. A standardized statistic can be negative TRUE FALSE 4. We run tests of significance to determine whether ðÌ is larger or smaller than some value. TRUE FALSE 5. We run tests of significance to determine whether ï° is larger or smaller than some value. TRUE FALSE 6. Dwayne Wade of the Miami Heat hit 569 of his 1093 field goal attempts in the 2012/2013 season for a shooting percentage of 52.1%. Over the lifetime of Dwayneâs career, can we say that Dwayne is more likely than not to make a field goal? a. Is the long-run probability of Dwayne making a field goal a parameter or a statistic? b. Is 52.1% a parameter or a statistic? c. When simulating possible outcomes assuming the chance model, how many times would you flip a coin for one repetition of the 2012/2013 season? d. With each repetition, what would you keep track of? e. What would be a typical value from a single repetition? June 27, 2014 MAA PREP workshop 40
