When Ho: p = 0.25 is true and n = 10 only, the probability of cornmitting Type I error is about 0.08 which is substantially greater than the fixed α = 0.05. This is an issue for practical use of the hypothesis testing. By changing the null value 0.01 p 0.5 and the sample size 10Sn 1000, investigate the probability of committing Type I error. a. Complete the following table by the probability of committing Type I error. (First, write...
