Problem (2) Solve using the formula (Handwrite your solution) A consumer agency wanted to estimate the difference in the mean amounts of caffeine in two brands of coffee. The agency took a sample of 15 one-pound jars of Brand I coffee that showed the mean amount of caffeine in these jars to be 80 milligrams per jar with a standard deviation of 5

Question 3 Suppose that the risk-free rate follows the following stochastic process: drt = a(b - rt) dt + vg(t)dB. 1. Denote Rt = eatrt. Using Ito's lemma, find the expression for dRut. 2. Solve for Rt and rt. In your answer, Rt and rt should be written as a sum of a deterministic term and an Ito integral. 3. When t approaches infinity, what does
