3. A wildlife refuge in South America has howler monkeys and spider monkeys. A biologist working there randomly selected eight adults of each type of monkey, weighed them, and recorded their weights in pounds.
howler monkey: {15, 16, 17, 17, 17, 17, 18, 19}
spider monkey: {12, 13, 13, 14, 14, 14, 16, 16}
(a) Calculate the mean and MAD for each type of monkey.
(b) Calculate the means-to-MAD ratio for the two types of monkeys.
(c) What inference can be made about the weight of both types of monkeys? Explain.

A = howler
B = spider

1) The means for the given data
a) 17
b) 14
2) The mean absolute deviation of the data
a) 0.75
