Consider a population with µ=93.3 and σ=5.27.
(A) Calculate the zscore for x=94.9 from a sample of size 12.
(B) Could this zscore be used in calculating probabilities using Table 3 in Appendix B of the text? Why or why not?

(A) z = (x  mean)/(sd/√n)
With your data:
z = (94.9  93.3)/(5.27/√12)
I'll let you finish the calculation.
(B) Do not have access to the table.
