Individuals age 75 and over averaged 0.15 hour (9 minutes) per day using a computer for leisure. Individuals ages 15 to 19 spend 1.0 hour per day using a computer for leisure. If these times follow an exponential distribution, find the proportion of each group that spends:

  1. Less than 8 minutes per day using a computer for leisure. (Round your answers to 4 decimal places.)

    Age 75 and over: 0.5890 (correct) Ages 15 to 19: _________

  2. More than 2 hours. (Round your answers to 4 decimal places.) Age 75 and over: 0.0000 (correct) Ages 15 to 19: _________

3. Between 16 minutes and 48 minutes using a computer for leisure. (Round your answers to 4 decimal places.)
