An experimenter needs to determine a sample size for their experiment. They want an 80% power and need to achieve 95% confidence in the study on a two tailed test. The experimenter expects a standard deviation of about 10 on the experiment, and a scientifically important difference is at 2.5. Using the sample size estimate from the previous equation and JAMOVI, what is the achieved power for this experiment
