Distributions Binomial Large sample sizes, use the normal distribution TI STAT TESTS 1-PropZ Test PHStat 1 Sample Tests Z test for the Proportion C) Calculate the Power and β of a test Step 1) Find the critical region using o μ . Step 2) Find the probability of being in the critical region assuming a particular value for Ha is true. This value = Power....
