Susаn is dоing а study tо determine hоw mаny women between the ages of 25 and 44 years of age get an annual pap smear which she plans to generalize to her state. She is randomly sampling a state data set from a large national HMO. There are 500 subjects in her sample.  When she reviews the data set for each subject, she discovers that the age is missing in almost 30% of the study subjects.  Her sample size calculations show that she must have a minimum of 450 study subjects for the level of significance she wants to achieve. What should she do?
