Question:
Estimating the age of glacial drifts. Refer to the American Journal of Science (Jan. 2005) study of the chemical makeup of buried tills (glacial drifts) in Wisconsin, presented in Exercise 2.192 (p. 135). The ratio of the elements aluminum (AI) and beryllium (Be) in sediment is related to the duration of burial. Recall that the AI/Be ratios for a sample of 26 buried till specimens were determined. The till specimens were obtained from five different boreholes
(labeled UMRB-1, UMRB-2, UMRB-3, SWRA, and SD).
The data are shown here. Conduct an analysis of variance of the data. Is there sufficient evidence to indicate differences among the mean AI/Be ratios for the five boreholes?
If so, which borehole has the highest mean ratio?
Test, using a = .10.
