Question 9. Description: Quality control engineers at the ACME Widget company have determined, through extensive life testing, that the operating life of their new Super-Modified Widget varies according to an exponential distribution, with an average lifetime of 60 months. Let the random variable X be the lifetime of a randomly selected Super-Modified Widget. a) What is the skewness of the distribution of the Super-Modified Widget lifetimes? Answer: b) What is the kurtosis of the distribution of the Super-Modified Widget lifetimes? Answer: c) What is the median lifetime of a Super-Modified Widget (ie., median of the distribution of X)? (Round your final answer to the nearest whole number of months). Answer: d) What is the probability that a randomly selected Super-Modified Widget operates for more than the mean lifetime? (Round the value to FOUR decimal places). Answer: e) What is the 75th percentile of the distribution of X? (Round the value to the nearest whole number of months)
