Anthropology. In their study of genetic groupings, anthropologists use a ratio called the cephalic index. This is the ratio of the breadth B of the head to its length L (looking down from above) expressed as a percentage. A study of the Gurung community of Nepal published in the Kathmandu University Medical Journal in 2005 found that the average head length of males was 18 cm, and their head breadths varied between .12 and 18 cm. Find the range of the cephalic index for males. Round endpoints to one decimal place.
