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 0.35 hour (21 minutes) per day using a computer for leisure. Individuals ages 15 to 19 spend 1.1 hour per day using a computer for leisure. If these times follow an exponential distribution, find the proportion of each group that spends: Less than 18 minutes per day using a...
