Class Project

Instructions:

Analyze the data set found in the class directory under the name etruscan_skulls.xls.

Description:

"The origins of the Etruscan empire remain something of a mystery to anthropologists. A particular question is whether Etruscans were native Italians or immigrants from elsewhere. In an anthropometric study, observations on the maximum head breadth (measure in \(\mathrm{mm}\) ) were taken on 84 skulls of Etruscan males. These data were compared with the same skull dimension for a sample of 70 modern Italian males." excerpted from "A Handbook of Small Datasets", Hand, Daly, Lunn, McConway and Ostrowski, Chapman & Hall, 1994.

Data source: Barnicott, N.A. and Brothwell, D.R. (1959) The evaluation of metrical data in the comparison of ancient and modern bones. In Medical biology and Etruscan origins, G.E. Wolstenholme and C.M. O'Connor, eds., Little Brown & Co., 136 .

Your report should include the following:

1. A graphical summary of the data set (more than one graph may be appropriate - you decide).
2. Numerical summaries of the data set (you decide which is best).
3. Does the evidence suggest that Etrusean males had an average maximum head breadth of more than \(143 \mathrm{~mm}\) ?
4. Does the evidence suggest that modern Italian males have an average maximum head breadth of less than \(133 \mathrm{~mm}\) ?

Part 2: EXTRA CREDIT

Analyze the data set found in the class directory under the name normtemp_data.xls. Temperature is measured in degrees \(\mathrm{F}\), for the gender column 1= male, 2= female, and heart rate is measured in beats per minute.

We are all familiar with the notion that the mean normal body temperature is 98.6 degrees F. What is surprising is that recent medical research has posited that the mean normal temperature is really 98.2 degrees F! The attached data were derived from an article in the Journal of the American Medical Association entitled "A Critical Appraisal of 98.6 Degrees \(\mathrm{F}\), the Upper Limit of the Normal Body Temperature, and Other Legacies of Carl Reinhold August Wunderlich" (Mackowiak, Wasserman, and Levine 1992).

Your data analysis should address the following questions:

- Is the true population mean really 98.6 degrees F?

- Is the distribution of temperatures normal?

- At what temperature should we consider someone's temperature to be "abnormal"?

- Is there a significant difference between males and females in normal temperature?

- Is there a relationship between body temperature and heart rate?
