The National Highway traffic Safety Administration requires each U.S. state to carry out an observational study to assess the level of seat belt use in the state. One reportsummarized data from a study done in a certain state. The proportions in the accompanying table are based on observations of over 25,000 drivers and passengers.MaleFemaleUses Seatbelt Does Not Use Seat Belt0.420.4550.080.045Assume that these proportions are representative of adults in this state and that an adult from this state is selected at random.(a) What is the probability that the selected adult does not use a seat belt given that the selected individual is female?(b) What is the probability that the selected individual is female given that the selected individual does not use a seat belt?(c) Are the probabilities from parts (a) and (b) equal? Write a couple of sentences explaining why or why not.They --Select--- ✓ equal. Part (a) is the proportion of [---Select------Select---and part (b) is the proportion ofV. There is ---Select--- reason to believe that these proportions should be equal.I
