    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    A sample mean, sample size, and population standard deviation are given. Use the P-value approach to perform a one-mean z-test about the mean of the population from which the sample was drawn.

    x bar= 78, n = 28, sigma = 11, Hnought: mu=72, Hone: mu>72 , alpha = 0.01

    First find the proper z value then use this to find the p-value.
    Enter the p-value - x.xxxx

    Please explain step-by-step how to solve this hypothesis testing problem.
