Archaeologists can determine the diets of ancient civilizations by measuring the ratio ofcarbon-13 to carbon-12 in bones found at burial sites. Large amounts of carbon-13 suggest adiet rich in grasses such as maize, while small amounts suggest a diet based on herbaceousplants. The article "Climate and Diet in Fremont Prehistory: Economic Variability andAbandonment of Maize Agriculture in the Great Salt Lake Basin" (J. Coltrain and S.Leavitt, American Antiquity, 2002:453-485) reports ratios, as a difference from a standardin units of parts per thousand, for bones from individuals in several age groups. The data arepresented in the following table.RatioAgeGroup(years)0-11 17.2 18.4 17.9 16.6 19.0 18.3 13.6 13.5 18.5 19.1 19.1 13.412-24 14.8 17.6 18.3 17.2 10.0 11.3 10.2 17.0 18.9 19.225-45 18.4 13.0 14.8 18.4 12.8 17.6 18.8 179 18.5 17.5 18.3 15.2 10.8 19.8 119.2 15.4 13.246+ 15.5 18.2 12.7 15.1 18.2 18.0 14.4 10.2 16.7Construct an ANOVA table. You may give a range for the P-value.b. Can you conclude that the concentration ratios differ among the age groups?a.

A certain species of tree has an average life span of 130 years. A researcher has noticed a large number of trees of this species washing up along a beach as driftwood. She takes core samples from 27 of those trees to count the number of rings and measure the widths of the rings. Counting the rings allows the researcher to determine the age of each tree. Her data are displayed in the provided table. 98 79 147 200 130 60 51 127 105 75 120 113 200 190 81 98 160 165 134 62 152 66 68 124 190 159 60 One of her interests is determining if this sample provides evidence that the average age of the driftwood is less than the 130 year life span expected for this type of tree. If the average age is less than 130 years it might suggest that the trees have died from unusual causes, such as invasive beetles or logging. Use technology to create a randomization distribution with at least 1,000 values…
