Question: Assume that development time for a particular type of photographic printing paper when exposed to a light source for 5 seconds is normally distributed with a mean of 25 seconds and standard deviation of 1.3 seconds. (5 points)

a. What is the probability a particular print will required more than 26.5 seconds to develop? (1)

b. What is the probability that the development time is at least 23 seconds? (1)

c. What is the probability that the development time differs from the expected time by more than 2.5 seconds? (3)
