Power: Alternative sampling density tail beyond crit value
With a sample size of 100, when the variance is 26.02
·Probability of observing an estimate (sample
mean) greater than 1 is 0.025 when the mean is 0
·Probability
of observing an estimate (sample mean) greater than 1 is 0.800 when
the mean is 1.43
·Probability of observing an estimate (sample
mean) greater than 1 is 0.975 when the mean is 2
(Power under the null hypothesis is the size of the test.)
