Question 2: Exponential distribution The distance X between two successive faults in a metallic wire is an exponential random variable with parameter A = 1.3 faults per cm (centimeter). Answer the following questions. 1. Calculate the probability of P(X<1) 2. Find the probability of P(o.9 < Xs 1.7) 3. Calculate the probability that the distance between two successive faults will be greater than 3 mm (millimeters)
4) Computing the standard deviation ơ, of N measurements y,,y1,...yy of a singles quantity y requires that you compute the sum (y, - j). Prove that this sum can be rewritten as i=1 N i=1 i=1 This problem is a good exercise using summation notation. Many calculators use the expression on the right to compute the standard deviation. Can you determine why?
