An electronic product with n identical parts connected in series cannot function properly if any ofthe parts fail.When the life span of each part follows exp()) and is independent to each other, answer thefollowing questions.(1) The random variable Y is the lifetime of this electronic product. Find the distribution of Y.(e.g. normal distribution, binomial distribution, etc.)(2) Find the distribution of Z = 2nλY (e.g. normal distribution, binomial distribution, etc.)(3) Use number (2) to find the (1 - α) × 100% confidence interval of λ when n = 10.

Ch6. "A carpet manufacturing company is comparing the tensile strengths of two different types of synthetic fiber. Synthetic fiber A used in manufacturing carpet has tensile strength that is normally distributed with mean 75 psi and standard deviation 8 psi, and synthetic fiber B has tensile strength that is 75 psi and standard deviation 12 psi. Random sample of nA = 16 and nB = 9 of fiber specimens are selected. Find the probability that the sample mean of fiber specimen A exceeds the sample mean of fiber specimen B by 4."
Coal is carried from a mine in West Virginia to a power plant in New York in hopper cars on a long train. The automatic hopper car loader is set to put 53 tons of coal into each car. The actual weights of coal loaded into each car are normally distributed, with mean u = 53 tons and standard deviation o = 1.3 ton. n USE SALT (a) What is the probability that one car chosen at random will have less than 52.5 tons of coal?
