Bat characteristics
Biologists know that bats have different flight characteristics. Some bats exhibit fast, straight, and long flights; others are moderately slow, and highly maneuverable. The flight capabilities of bats are presumably a function of (a) the characteristics of the bat wings, and (b) the laws of physics. The data presented below are wing spans in centimeters for certain species of bats from Nicaragua and Costa Rica. Two categories of bat species are represented: fruit-eaters and insect-eaters.
Fruit eaters:
25.2, 27.2, 42.0, 44.8, 31.3, 32.5, 32.0, 28.1, 30.7, 27.0, 41.1, 41.6, 58.4, 58.7, 53.9
Insect eaters:
32.8, 27.4, 21.0, 23.9, 27.5, 22.4, 18.7
(a)Construct two dotplots that will allow you to easily compare the distributions of the wing spans for the two categories of bats, fruit-eaters and insect-eaters.
(b)Write a short paragraph describing the features of the two plots; what do these plots tell you about the differences in wing span for fruit- and insect-eaters?
