Cheek teeth of extinct primates. Refer to the American Journal of Physical Anthropology (Vol. 142, 2010) study of the dietary habits of extinct mammals, Exercise 3.25 (p. 121). Recall that 18 cheek teeth extracted from skulls of an extinct primate species discovered in western Wyoming were analyzed. Each tooth was classified according to degree of wear (unworn, slight, light-moderate, moderate, moderate-heavy, or heavy), with the 18 measurements shown in the accompanying table. (These data are saved in the CHEEKTEETH file)

a. Suppose the researcher will randomly select one tooth from each wear category for a more detailed analysis. How many different samples are possible?

b. Repeat part a, but do not include any teeth classified as “unknown” in the sample.

Exercise 3.25

Cheek teeth of extinct primates . Refer to the American Journal of Physical Anthropology (Vol. 142, 2010) study of the dietary habits of extinct mammals, Exercise 2.7 (p. 34). Recall that 18 cheek teeth extracted from skulls of an extinct primate species discovered in western Wyoming were analyzed. Each tooth was classified according to degree of wear (unworn, slight, light-moderate, moderate, moderate-heavy, or heavy). The 18 measurements are reproduced in the accompanying table and saved in the CHEEKTEETH file. One tooth is randomly selected from the 18 cheek teeth. What is the probability that the tooth shows a slight or moderate amount of wear?

Museum management. Refer to the Museum Management and Curatorship (June 2010) study of the criteria used to evaluate museum performance, Exercise 2.19 (p. 37). Recall that the managers of 30 leading museums of contemporary art were asked to provide the performance measure used most often. A summary of the results is reproduced in the table. One of the 30 museums is selected at random. Find the probability that the museum uses big shows most often as a performance measure.

Exercise 2.7

Cheek teeth of extinct primates. The characteristics of cheek teeth (e.g., molars) can provide anthropologists with information on the dietary habits of extinct mammals. The cheek teeth of an extinct primate species was the subject of research reported in the American Journal of Physical Anthropology (Vol. 142, 2010). These data are saved in the CHEEKTEETH file. A total of 18 cheek teeth extracted from skulls discovered in western Wyoming were analyzed. Each tooth was classified according to degree of wear (unworn, slight, light-moderate, moderate, moderateheavy, or heavy). The 18 measurements are listed here.

a. Identify the variable measured in the study and its type (quantitative or qualitative).

b. Count the number of cheek teeth in each wear category.

c. Calculate the relative frequency for each wear category.

d. Construct a relative frequency bar graph for the data.

e. Construct a Pareto diagram for the data.

f. Identify the degree of wear category that occurred most often in the sample of 18 cheek teeth.

Exercise 2.19

Museum management. What criteria do museums use to evaluate their performance? In a worldwide survey reported in Museum Management and Curatorship (June 2010), managers of 30 leading museums of contemporary art were asked to provide the performance measure used most often. A summary of the results is provided in the table. The researcher concluded that “there is a large amount of variation within the museum community with regard to . . . performance measurement and evaluation.” Do you agree?
