What are the steps for solving the z-score

  1. Sep 19, 2009 #1
    Human body temperatures are normally distributed with a mean of 98.20 and a standard deviation of 0.62.
    Find the body temperature corresponding to a z-score of z=1.73



    What are the steps to solve this problem.

    Well, clearly whoever gave you this problem expects you to know that if x is from a normal distribution with mean [itex]\mu[/itex] and standard deviation [itex]\sigma[/itex] then the corresponding z, for the standard normal distribution, is given by
    [tex]\frac{x- \mu}{\sigma}[/tex]

    Since here you are given z, put the given values into the equation and solve for x.
