Extracted text: The standard normal distribution is a continuous distribution with a mean of 0 and a standard deviation of 1. The following is true: About 68% of all outcomes lie within I St.Dev. About 95% of all outcomes lie within 2 St.Devs About 99.97% of all outcomes lie within 3 St. Devs. The probability/percentage/percentile for a nomal distribution is the area under the curve. You will ALWAYS BE CALCULATING OVER AN INTERVAL. Values outside of 2 St. Devs. are considered "unusual values." X-H value- mean St.Dev Recall that 21. The salaries of employees in a large company are normally distributed with a mean of S60,000 and a standand deviation of $10.0.
