Question: A researcher is evaluating the influence of a treatment using a sample selected from a normally distributed population with a man of = 80 and a standard deviation of = 20. The researcher expects a 12-point treatment effect and plans to use a two-tailed hypothesis test with = .05.
- Compute the power of the test if the researcher uses a sample of n = 16 individuals.
- Compare the power of the test if the researcher uses a sample of n = 25 individuals.
