Suppose that monthly income follows a normal distribution with µ = $4,300 and σ = $1,500. A government agency wants to provide free health care for all individuals who fall below a specific monthly income level but does not want to award this benefit to more than 33% of the population. What is the income cutoff for this proposed benefit where no more than 33% of the population will qualify (in other words, will fall below this level of income)?
