Product warranty. Graph the probability density function for Problem 44 over the interval [0, 3], interpret part (B) of Problem 44 geometrically, and describe the geometric representation.
44. Product warranly. A manufacturer warrants a product for parts and labor for 1 year and for parts only for a second year. The time to a failure of the product after it is sold is given by the probability density function

The respective densities of the two distributions are given by Sx (x) = (1/2) exp (-x/à), x > 0, 2 > 0; S(2) =- T(a) 2-l exp(-8i), 2 > 0. Given that the Pareto pdf given by fx (x) = (5 +x)ª+1 * > 0, a > 0, 8> 0. (a) Show that the marginal distribution of losses follows a Pareto distribution, i.e. P(a, 5). (b) Use the mixing formulation of the Pareto to deduce that if X~P(a, 5), then E (X) = .arrow_forward

Suppose the probability that any particular couple or individual arrives late is 0.41 (a couple will travel together in the same vehicle, so either both people will be on time or else both will arrive late). Assume that different couples and individuals are on time or late independently of one another. Let X = the number of people who arrive late for the seminar.

Read It Watch It 4arrow_forwardPresbyopia affects most people at the age of 40 years. It does not affect the life expectancy but diminish visual functions. After vision declines at the age of 40, it does not (hypothetically) decline more with advancing age. There is a new surgical procedure for this condition that restore vision to normal with no complication and costs INR. 100000. Life expectancy at the age of 40 in the general population is assumed to be 42 years and time trade off yields a utility value of 0.9 for presbyopia.

- Probability.arrow_forward5. A group of doctors are conducting a clinical trial for an experimental cancer drug. The graph below shows the probability of patient survival as a function of time, t (in months). The functions for Streated (survival probability of patients treated by the drug) and Splacebo (survival probability of patients given a placebo) are determined to be: Streated(t) = e-() and Splacebo (t) = e #. Use the given function (a) Splacebo (t) = e-i to calculate the average survival probability of the placebo group for the first 10 months of the study. Round to 2 decimal places.
