The standard normal probability distribution: the standard normal distribution has mean of 0 and standard, a z-value or standard normal value is the distance between a selected deviation of 1. It is also called the z distribution. value, designed x and the population mean m , divided by the population standard deviation s . The bi-weekly starting salaries of recent mba graduates from ryerson. University follows the normal distribution with a mean of ,500 and a standard deviation of . What is the z-value for a salary of ? m-= x s z. 2 : approximately 99. 7 percent of the area under the normal curve is within three standard deviations of the mean m. Assume that the annual earnings of all employees with certified.
