Suppose I interview a random sample of 300 adults and ask them to assess their health, from “Poor” to “Excellent.” These are my results. (a) What is the proportion of individuals in poor health in this sample (to 3 decimal places)? In addition to giving the proportion, please show the numerator and denominator. (b) What is the proportion of individuals in the sample who are in “good” or better health (to 3 decimal places)? Again, in addition to giving
