15 See Figure 11.1, Cancer incidence at various ages for men and women. p. 400. Weinberg. Note maximum incidence per 100,000 population at about age 70, then drop off after that age. Serious incidence begins around age 35 except for breast cancer which can have an earlier onset depending on genetics. Incidence of Various Kinds of Cancers in Men and Women as a Function of Age

54 A Note About Completing Matching Questions 1.Each response in column B can be used only once. 2.Strike off a response from Column B when you use it in column A. 3.You have to match the best response from column B to the item in column A, not just one that might fit. 4.If you use a less-than-optimal response from Column B, you won’t have that response when you need it. 5.Answer the matching items that you are completely sure about. 6.That reduces the number of options you have to deal with. 7.The more you actually know for sure, the easier this kind of question is because it reduces your uncertainties to a very low number of options.

55 This slide will be set to anonymous so it should say “Not accepting user data”. Your response is important so please provide your opinion. Please respond to the following: This review for the mid-term exam was 1.Not very useful and not worth doing. 2.Reasonably useful. Overall worth doing. 3.A really good idea. You should do it for other exams. 0 of 95
