Researchers at UCLA were interested in whether working mothers were more likely to suffer workplace injuries than women without children. They studied 1400 working women, and a summary of their findings was reported in the San Luis Obispo Telegram-Tribune

(February 28, 1995). The information in the following table is consistent with summary values reported in the article:

No Children Children Under 6 Children, but None Under 6 Total Injured on the Job in 1989 32 68 56 156 Not Injured on the Job in 1989 368 232 644 1244 Total 400 300 700 1400 The researchers drew the following conclusion: Women with children younger than age 6 are much more likely to be injured on the job than childless women or mothers with older children. Provide a justification for the researchers’ conclusion. Use the information in the table to calculate estimates of any probabilities that are relevant to your justification.
