Individuals age 75 and over averaged .25 hour (15 minutes) per day using a computer for leisure. Individuals ages 15 to 19 spend .8 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 13 minutes per day using a computer for leisure. (Round your answers to 4 decimal places.)

Proportion 

(b) More than two hours. (Round your answers to 4 decimal places.) 

Proportion 

(c) Between 26 minutes and 78 minutes using a computer for leisure. (Round your answers to 4 decimal places.)

Proportion 

(d) Find the 32th percentile. Sixty eight percent spend more than what amount of time? (Round your answers to 2 decimal places.)
