Read the following scenario:
Park Rangers in a Yellowstone National Park had determinedthat fawns less than 6 months old have a body weight that is approximatelynormally distributed with a mean u=26.1kg and standard deviation o=4.2 kg. Letx be the weight of a fawn in kilograms.
Complete each of the following steps for the word problemsbelow:
-
Rewrite each of the following word problems intoa probability expression, such as P(x>30).
-
Convert each of the probability expressions involvingx into probability expression with the appropriate area shaded.
-
Solve the problem.
