Question

The business analyst at vodacom in an analysis of the firm's customers in Durban found that the customers who phoned for technical support had to wait for a customer service representative an average of 28 minutes with a standard deviation of 5.5 minutes. The firm's past transaction records showed the wait times to be normally distributed . she wants to know what would be the likelihood that a customer phones vodacom and gets service in less than 10 minutes

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
