Roger has read a report that the weights of adult mail Siberian tigers have a distribution which is approximately normal with mean μ = 390 lb and σ = 65 lb.
a) Find the probability that an individual male Siberian tiger will weigh more than 450 lb.
Find the t-score for 450:
t(450) = (450-390)/65 = 0.9231...
----------
P(0.9231 < t < 10 for df=large) = 0.1791
