The per capita disposable income for residents of a U.S. city in a recent year is normally distributed, with a mean of about $44,000 and a standard deviation of about $2450. Find the probability that the disposable income of a resident is more than $45,000. Round z to the nearest hundredth and P to the nearest ten thousandth. 0.04 P = 0.4840 Is this an unusual event?
