Refer to the American Journal of Physical Anthropology (Vol. 142, 2010) study of the characteris-tics of cheek teeth (e.g., molars) in an extinct primate species, Exercise 2.34 (p. 46). The data ondentary depth of molars (in millimeters) for 18 cheek teeth extracted from skulls are reproducedbelow18.12 16.5519.48 15.7019.36 17.8315.94 13.2515.83 16.1219.70 18.1315.76 14.0217.00 14.0413.96 16.20Table 1: Data on Dentary Depth (mm) of Molars
Find the range of the data set. If the largest depth measurement in the sample were doubled, how would therange change? Would it increase or decrease?b. Find the variance of the data set. If the largest depth measurement in the sample were doubled, howwould the variance change? Would it increase or decrease?c. Find the standard deviation of the data set. If the largest depth measurement in the sample were doubled, howwould the standard deviation change? Would it increase or decrease?
