Please see picture below. Question 9 (need to answer all parts of question: a, b, c, d, & e!) round to correct decimal places for each part (lists number to round to for each). Thank you!

Description: 9. 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? b) What is the kurtosis of the distribution of the Super-Modified Widget lifetimes? c) What is the median lifetime of a Super-Modified Widget (i.e., median of the distribution of X) ? (Round your final answer to the nearest whole number of months). 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). e) What is the 75th percentile of the distribution of X? (Round the value to the nearest whole number of months)
