Although bats are not known for their eyesight they are, Ask an Expert

Statistics

Although bats are not known for their eyesight, they are able to locate prey (mainly insects) by emitting high-pitched sounds and listening for echoes. A paper appearing in Animal Behaviour ("The Echolocation of Flying Insects by Bats" [1960]: 141-154) gave the following distances (in centimeters) at which a bat first detected a nearby insect:

62 23 27 56 52 34 42 40 68 45 83

a. Compute the sample mean distance at which the bat first detects an insect.

b. Compute the sample variance and standard deviation for this data set. Interpret these values.
