To determine a target audience for a new software package, a computer company surveyed a large random sample of potential customers, asking each whether he/she uses a previous version of the software 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 according to two variables: the age of the respondent ("under 18", "18-35", "36-54", "55+") and software use ("on a regular basis" or "not on a regular basis"). Each cell of the table contains three numbers: the first number is the observed cell frequency (f); the second number is the expected cell frequency (f) under the assumption that there is no dependence between age and software use and the third number is the following value. (Observed cell frequency - Expected cell frequency)² (fo-fe) fE Expected cell frequency The numbers labeled "Total" are totals for observed frequency.
