A TV system is expected to last for 50000 hours before failure. Assume an exponential distribution for the time until failure.
a) is the distribution skewed or symmetric?
b) what is the standard deviation of the length of time until failure?
c) the system has been working continuously for the past 8500 hours and is still on. What is the expected time from now until failure?

The number of hours a battery lasts before failing follows an
exponential distribution with a mean of μ = 24.5 hours and a
standard deviation of 10 hours. Eric buys a pack of 64 batteries.
Find the probability that the average number of hours a battery
lasts is 21 hours or less.
a. 0.0026
b. 0.9974
c. 0.3632
d. -2.80

The failure time T (in hours of use) for a particular
electronics component follows an exponential distribution with
parameter λ. Find the probability that a failure time is somewhere
within 1 standard deviation of the mean failure time. Explain in
words what you did to solve this, and then tell me your final
answer.

A survey of 200 college students showed the distribution of the
number of hours of TV watched per week. The mean was found to be
3.66 hours with a standard deviation of 4.93. Assume the normal
model is appropriate. Find the number of hours of TV watched by top
25% of college students.

Suppose the time to failure follows an exponential distribution
with parameter λ. Based on type II censoring determine the
likelihood and the maximum likelihood estimator for λ. Assume that
n = 3 and the experiment ends after 2 failures.
