question 6

Multiple Choice

A sports researcher wanted to assess the likelihood that girls score more goals than boys do in five a-side soccer. She conducted one study where the probability of making a Type I error was 0.05 and a Type II error was 0.2. Does her research have empirical probability?

• A) No, to have empirical probability the likelihood of an effect being detected requires a series of repeated identical experiments, where the probability of making a Type I error is 0.05 and a Type II error is 0.2.
• B) No, to have empirical probability the likelihood of an effect being detected requires a series of repeated identical experiments, where the probability of making a Type I error is above 0.05 and a Type II error is 0.2.
• C) Yes, to have empirical probability the likelihood of an effect being detected requires a single experiment, where the probability of making a Type I error is above 0.05 and a Type II error is 0.2.
• D) No, to have empirical probability the likelihood of an effect being detected requires a single experiment, where the probability of making a Type I error is above 0.05 and a Type II error is 0.1.
