A type of casting iron has Hall-Petch parameters: σ0 = 36.3 MPa and K = 6.5 MPa ∙ mm^−0.5. For a given sample, the grain size distribution is shown in the diagram below. Each bar represents the percentage of grains in particular size. First, estimate the average grain size based on concept of “weighted mean” (in case you do not know, search for this term). Then, apply Hall-Petch Equation to calculate the yield stress. (Note: 1 μm = 0.001 mm)

96 Question 4 It is commonly believed that the mean body temperature of a healthy adult is 98.6^\circ F. You are not entirely convinced. You believe that it is different than 98.6^\circ F. The temperatures for 13 randomly selected healthy adults are shown below. Assume that the distribution of the population is normal. 82.8, 94.6, 92.1, 94.1, 92.9, .7, 90.7, 94, 72, 94, 97.2, 100.5, 86.6 What can be concluded at the a = 0.05 level of significance? %D a.

Study Finds Benefit of Tablet Every Other. Day Is Much Greater Than Expected Ву HAROLD M.SCHMECK Jr. A major nationwide study shows that a single aspirin tablet every other day can sharply reduce a man's risk of heart auack and death from heart at- tack. The lifesaving effects were so dra- matic that the study was halted in mid- December so that the results could be reported as soon as possible to the par- |ticipants and to the medical profession in general. The magnitude of the beneficial ef- fect was far greater than expected, Dr. Charles H. Hennekens of Harvard, principal investigator in the research, said in a telephone interview. The risk of myocardial infarction, the technical name for heart attack, was cut aimosi in half. 'Extreme Beneficial Effect A special report said the results showed "a statistically extreme benefi- ciał effect" from the use of aspirin. The report is to be published Thursday in The New England Journal of Medicine. In recent years smaller studies have…
