Consider a normal population with μ = 36 and σ = 4.9. Calculate the z-score for an x of 47.6 from a sample of size 14. (Give your answer correct to two decimal places.)
If you want expert help, please type your school subject in the appropriate box.
Z = (score-mean)/SD
If you know the mean and SD for the population, sample size is extraneous information for determining the Z score for an individual raw score.
Could this z-score be used in calculating probabilities using Table 3 in Appendix B? Why or why not?
