Suppose the time spent by a randomly selected student who uses a terminal connected to a local time-sharing computer facility has a gamma distribution with mean 20 min and variance 80 min2.
(a) What are the values of α and β?
| α = | |
| β = |
(b) What is the probability that a student uses the terminal for at
most 28 min? (Round your answer to three decimal places.)
(c) What is the probability that a student spends between 20 and 36
min using the terminal? (Round your answer to three decimal
places.)
just need c please

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...
