According to a report issued by the CDC in 2013, 66.8 % of women 40 years of age and over had a mammogram within the last two years. An oncologist at the CDC would like to know if there has been a change in this percentage over the last two years. A random sample of 717 women (40 and older) is taken, and each is asked the date of their last mammogram.
