... your decision rule in terms of z for rejecting a null hypothesis that the population mean is 500? In this case, each tail must contain 5%, so we look in the middle of the z-table for a value near 0.45, and we find that it corresponds to approximately 1.645 standard deviations from the mean. You can ...
