The lifetime of an electronic component has a Weibull distribution with parameters α=0.60 and β=2. Compute the probability the component fails before the expiration of a 4 year warranty. The maximum flood levels, in millions of cubic feet per second, for a particular U.S. river have a Weibull distribution with α=5/3 and β=3/2. Find the probability that the maximum flood level for next year will exceed 0.7 million cubic feet per second.

Suppose a car radiator useful lifetime has Weibull distribution with β = 1.5 and the mean lifetime of 150,000 miles. John has just bought a used car with 180,000 miles and original radiator which is still good. What is the probability that it’s going to last at least 20,000 miles more before needing replacement?

Assume that the life of an engine follows a normal distribution with an average life of 12 years and a standard deviation of 2 years

Assume that the life of an engine follows a normal distribution with an average life of 12 years and a standard deviation of 2 years. The seller replaces all engines that fail during the warranty period without additional charges.a) If the manufacturer wishes to replace only 1% of the engines it sells, what is the warranty time it must offer?b) supposes that Puerto Rico sold 30 engines, what is the percentage of probability that more than 1 customer will claim...
