- Suppose that Y1,Y2 are independent identically distributed (iid) random variables form a random sample from a probability distribution given by f(y)=θe^(−θy), y≥0 Suppose we observed a sample of size two (n=2): 0.04304550, 0.50263474. Read the data into R. Create a function in R to compute the log‐likelihood. Plot the likelihood function on a fine grid of θ values in R. Estimate the MLE of θ using Bisection, Secant, and Newton-Raphson methods in R.Suppose the inter-arrival time of people using the elevator can be modeled as X ~ Exp(1/6) (in minutes). What is the distribution of the number of people waiting at an elevator in two minutes (since the last elevator left)? Hint: Let Tn be the time when the n-th person arrives at the elevator, and let N be the number of people waiting at time t, then P(N>=n) if and only P(Tn =n) and P(N>=n+1). The difference of the two gives you P(N=n).Let X₁, X₂ be IID with \Exp(1), the standard exponential distribution. Show that Z = X₁/X₂ has an F-distribution.
