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 .15 hour (9 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 11 minutes per day using a computer for leisure
More than two hours
Between 22 minutes and 66 minutes using a computer for leisure
Find the 24th percentile. 76 percent spend more than what amount of time
