A public health researcher is estimating the potential need for specialized mental health services in a metropolitan area with a population of 500,000 people. The services are for an anxiety disorder characterized by an intense fear of situations where escape might be difficult, such as using public transportation, being in open or enclosed spaces, or being in a crowd. If the established lifetime prevalence for this disorder is 1.4%, approximately how many individuals in this population are expected to experience the disorder at some point in their lives?

A public health official is planning mental health services for a city with a population of 500,000 adults. Research indicates that about 1.4% of the population will, at some point in their life, experience an anxiety disorder defined by intense fear and avoidance of situations where escape might be difficult or help unavailable. Based on this information, what is the most reasonable estimate for the number of people in this city who will experience this disorder in their lifetime?
