To determine a target audience for a new software package, a computer company surveyed a large sample of potential customers, asking each whether he or she uses the older version of the software on a regular basis. (The company considered "a regular basis" to be at least three times a week.) The customers were classified according to two variables: age ("Under 18", "18-35", "36-54", or "551") and software use ("On a regular basis" or "Not on a regular basis"). The respective observed frequencies are written in the cells of the contingency table below. In addition, three of the cells have blanks beneath the observed frequencies. Fill in these blanks with the frequencies expected if the two variables, software use and age, are independent Round your answers to two or more decimal places.
