A biology researcher is studying the risk of extinction of a rare tree species in a remote part of the Armazon. In the course of her study, the researcher models the trees' ages using a normal.distribution with a mean of 251 years and a standard deviation of 50 years. Use this table or the ALEKS calculator to find the percentage of trees with an age between 187 years and 229 years according to the model. For your intermediate computations, use four or more decimal.places. Give your final answer to two decimal places (for example 98.23%).
