Problem 2. When conducting screening, public health professionals often have to anticipate the level of resources needed as a result of the screening. This includes resources to deal with issues related to false positive and false negative results. In this hypothetical example, a screening of a community was conducted to detect breast cancer among women 40 years of age and older. 12. Use the information below to construct an appropriate fourfold table, including appropriate column/row titles, column/row labels, and marginal totals. Use the information in the fourfold table to perform the calculations requested and answer the questions.

Positive Predictive Value 14. Negative Predictive Value Questions 15. About how many false positive screening results can be anticipated (round to nearest whole number using conventional rounding technique)? [0] (1 point) 16. About how many false negative screening results can be anticipated (round to nearest whole number using conventional rounding technique)? [0] (1 point) 17. What are the strengths of this screening test, any (think validity measures)? (2 points) 18. What are the weaknesses of this screening test, if any (think validity measures)? (2 points)
