Consider a population with µ=73.6 and 0 = 5.38
(A) Calculate the zscore for x =72.7 from a sample of size 45.
(B) Could this zscore be used in calculating probabilities using Table 3 in Appendix B of the text? Why or why not?

(A) Z = (scoremean)/SD if x = raw score.
Z = (scoremean)/SEm if x = mean, with SEm = SD/√(n1)
(A) We do not have access to your table.
