Question
The lifetime, X, of a particular integrated circuit has an exponential distribution with rate of λ=0.5 per year. Thus, the density of X is:
f(x,x) = 1 e-^x for 0 ≤ x ≤ ∞o, λ = 0.5. λ is what R calls rate.
Hint: This is a problem involving the exponential distribution. Knowing the parameter for the distribution allows you to easily answer
parts a,b,c and use the built-in R functions for the exponential distribution (dexp(), pexp(), qexp()) for other parts. Or (not
recommended) you should be able to use the R integrate command with f(x) defined as above or with dexp() for all parts.
d) What is the probability that X is greater than its expected value?
e) What is the probability that X is > 5?
f) What is the probability that X is> 10?
g) What is the probability that X > 10 given that X > 5?
h) What is the median of X?
