1. sam peabody is a wildlife researcher in australia. he has been studying red-bellied black snakes and tiger snakes. he randomly selected eight adults of each type of snake, measured them, and recorded their lengths in cm. red-bellied black snake: {145, 150, 150, 160, 170, 170, 170, 175} tiger snake: {120, 130, 134, 142, 146, 146, 149, 150} (a) create a line plot for each data set. (b) calculate the mean and mad for each type of snake. (round to the nearest tenth) (c) calculate the means-to-mad ratio for the two types of snakes. (d) what inference can be made about the length of both types of snakes? explain.
