Question

In Ventura County in 2013, it was thought that 16% of women over 40 had not had a mammogram in the last two years. Suppose a random sample of 140 of these women shows that 28 of them said they had not had a mammogram in the last two years.
a. What is the observed frequency of women who said they had not had a mammogram within the last two years?
b. What is the observed proportion of women who said they had not had a mammogram within the last two years?
c. What is the expected number to not have been screened (out of 140) if 16% is the correct rate? (Do not round off.)
