A researcher wants to determine the specificity of mammograms to determine how effective they are at diagnosing women who have breast cancer. Assume the researcher obtained the results below from a study:
Out of a total of 18 women with breast cancer, 12 screened positive and 6 screened negative on the mammogram.
Out of a total of 82 women without breast cancer, 5 screened positive and 77 screened negative on the mammogram.
Calculate and interpret the specificity of mammograms for detecting breast cancer.
