Exercise #2: Consider НA: μ Ho Compute the sample size required to achieve following power levels: a.) • σ = 25 · Effect size=5 • α = 5% · & = 80% b.) Same as above, but using 4 = 90% What happens to the required sample size when the power level is increased. c.) Same as in part a.) but using effect size = 15 What happens to the required sample size when the effect size is increased. d.) Same as in part a.) but using a = 10% What happens to the required sample size when the significance is increased. e.) For effect size = 5, what is the value of μA Q Search
