Consider a population with u=70.2 and o=4.61. (A) Calculate the zscore for x=73.2 from a sample of size 10. (B) Could this zscore be used in calculating probabilities using Table 3 in Appendix B of the text? Why or why not?

I take it u=µ and o=σ? I can't help you with what Appendix B is in your book, but I can show you the zscore formula.

Yeah the symbols are that way and I think I have the zscore formula but could use a refresher

\[\huge z=\frac{xµ}{s_x}\] \[\huge s_x = \frac{σ}{√n}\]

Cool. Use those formulas, and you should be fine. Try here for more info: http://stattrek.com/probabilitydistributions/standardnormal.aspx?tutorial=ap http://stattrek.com/sampling/samplingdistribution.aspx?Tutorial=AP

Thank you so much so far everything I have looked at including my text book has been confusing.

Stats is a messy place. It takes a strong combination of mathematical skill and good ol' common sense. Good luck!
