Question 863298: The Bureau of Labor Statistics’ American Time Use Survey showed that the amount of time spent using a computer for leisure varied greatly by age. Individuals age 75 and over averaged .25 hour (15 minutes) per day using a computer for leisure. Individuals ages 15 to 19 spend .9 hour per day using a computer for leisure. If these times follow an exponential distribution, find the proportion of each group that spends:
a)Less than 14 minutes per day using a computer for leisure. (Round your answers to 4 decimal places.)

Hi

Using a POISSON Distribution

P(x <14min) = .3632 0r 36.32% for  75 and older(avg 15min)

P(x <14min) = 2.4626x10^-11  for ages 15 - 19(avg 54min) , basically 0%
