A person involved in health promotion wanted to examine the likelihood that health promotion messages on social media would be more effective than in print media. 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 above 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 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.

Empirical probability refers to the probability that an event will occur based on the results of repeated trials of an experiment. In this case, the researcher conducted one study, so it does not have empirical probability. However, in order for an experiment to have empirical probability, it does not necessarily require repeated identical experiments with the same Type I and Type II error probabilities. The probability values of Type I and Type II errors are specified by the researcher, and the experiment can be repeated with different values for these probabilities.
