Losses have a uniform distribution from 0 to 250. An insurance pays 100% of the amount of a loss in excess of an ordinary deductible of 23. The maximum payment is 210 per loss. Determine the expected payment, given that a payment has been made.

The normal distribution has parameters μ and σ. The possible values for μ are all numbers on the real line, while σ must be positive. Write an R function that takes in a vector with two elements theta(whose values are unrestricted) and returns a list with two elements. The first element is to represents μ,mu=theta[1], and the second element is to represent σ,sigma=exp(theta[2]). Write a function that takes in a named list for mu and sigma and returns theta.

1) Rate data often follow a lognormal distribution. Average power usage (dB per hour) for a particular company is studied and is known to have a lognormal distribution with parameters μ = 4 and σ = 2. What is the probability that the company uses more than 270 dB during any particular hour? 2) A certain type of device has an advertised failure rate of 0.01 per hour. The failure rate is constant and the exponential distribution applies. (a) What...
