To determine a target audience for a new email package, a computer company surveyed a large sample of potential customers, asking each whether he or she uses email on a regular basis. (The company considered "a regular basis" to be at least three times a week.) The data, as summarized in the contingency table below, were classified by the age of the respondent and the response to the question.

The respective observed frequencies are written in the cells of the table. In addition, three of the cells have blanks beneath the observed frequencies. Fill in these blanks with the frequencies expected if the two variables,email useandage, are independent.

Round your responses to at least two decimal places.
