Individuals age 75 and over averaged .20 hour (12 minutes) per day using a computer for leisure. Individuals ages 15 to 19 spend 1.3 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 10 minutes per day using a computer for leisure. (Round your answers to 4 decimal places.) Proportion ________and ________.

(b) More than two hours. (Round your answers to 4 decimal places.)  Proportion ________ and ________. (c)  Between 20 minutes and 60 minutes using a computer for leisure. (Round your answers to 4 decimal places.) Proportion (d) Find the 26th percentile. Seventy four percent spend more than what amount of time? (Round your answers to 2 decimal places.)
