How many subjects be studied in each of two equal sized groups to achieve 80% power to detect a differentiate of 0.5 between the null hypothesis that both group means are 0.0 and the alternative hypothesis that the mean of group 2 is 0.5? Assume that the group standard deviations are 1.0 in both groups. Make your calculation assuming a two-sided two-sample t-test with a type I error (alpha) of 0.056
a. 6
b. 9
c. 17
d. 64
e. 253
