If the expected difference is 0.10 ln units, then what is the power of such a study
Question:
If the expected difference is 0.10 ln units, then what is the power of such a study if a two-sided test is to be used with α = .05?
Diabetes
Plasma-glucose levels are used to determine the presence of diabetes. Suppose the mean ln (plasma-glucose) concentration (mg/dL) in 35- to 44-year-olds is 4.86 with standard deviation = 0.54. A study of 100 sedentary people in this age group is planned to test whether they have a higher or lower level of plasma glucose than the general population.
