Chapter 7, Problem 85(choose chapter or problem)
Probability The a\erage lengths (from heak to tail) ofdifferent species of warblers in the eastern United States areapproximately normally distributed with a mean of 12,9centimeters and a standard deviation of 0.45 centimeter (seefigure). The probability that a randomly selected warbler has alength between n and /> centimeters isF[a < A < b) = ^-= t,-(--i:-J)7:(0'J5)^j^.^ 0.95v2 7tJ.,Use a graphing utility to approximate the probability that arandomly selected warbler has a length of (a) 13 centimeters orgreater and (b) 15 centimeters or greater. iSoiiicc: Peicrxoii'sField Guide: Eastern Birds)
