The distance, x, between laws on a long cable has an exponential distribution with a parameter f(x,x) = 1 ex for 0 ≤ x ≤ ∞, λ = b) What is the variance of X? is what R calls rate. c) What is the standard deviation of X? 12 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. a) What is the expected value of X? .Thus, the density of
