3. According to the U.S. Department of Health and Human Services (2021), the poverty rate for a four-person household in 2021 was $26,500. To bring attention to how low salaries are for first officers at regional airlines, let's assume that an aviation student researcher at a local university acquired a convenience sample of n = 75 first officers working at regional airlines throughout the United States. Let's further assume that the salaries approximated a normal distribution with a mean of $40,500 and a stand- ard deviation of $5,045. If 20 of the 75 participants live in a four-person household, are any of these first officers' salaries at the poverty rate? Why?
