Question 362596: The seasonal output of an experimental strain of pepper plants is carefully weighed. The mean weight of peppers per plant is 15 pounds, and the standard deviation of the normally distributed weights is 1.75 pounds. What is the probability that the output from a randomly selected plant weighs between 13 and 16 pounds?

Find the zscore for 13 and 16.
z=%28x-mu%29%2Fsigma
z%5B1%5D=%2813-15%29%2F1.75
z%5B2%5D=%2816-15%29%2F1.75
Then find P%28z%5B1%5D%29 and P%28z%5B2%5D%29

P%2813%3Cx%3C16%29=P%28z%5B2%5D%29-P%28z%5B1%5D%29
