Among the huge body of literature on smoking are data detailing the relative successfulness of males and females in quitting smoking. A study of 400 adults (ages 20 and older) who began various smoking-cessation programs produced the data in the contingency table below. The table shows data from the study regarding two variables: the smoker's sex ("male" or "female") and the length of the smoking cessation period ("less than two weeks", "between two weeks and one year", or "at least one year"). In the table, "less than two weeks" means that the individual returned to smoking within two weeks of beginning the program, "between two weeks and one year" means that the individual survived the first two weeks but returned to smoking within a year, and "at least one year" means that the individual did not smoke for at least a year after beginning the program. The cells of the table each contain three numbers. The first number in each cell is the observed cell frequency (o); the second number is the expected cell frequency (f) under the assumption that there is no association between sex and the length of the smoking cessation period; and the third number is the following value. (fo-fe) (observed cell frequency - Expected cell frequency)2 ƒE Expected cell frequency The numbers labeled "Total" are totals for observed frequency.
