Paper Details
A component has an exponential failure time distribution with a mean time to failure of 35 days.
(a) What is the probability that the component is still operating after 35 days?
(b) What is the probability that the component fails within 40 days?
(c) If six of these components are placed in series, what is the probability that the system is still operating after 5 days?
From his statistics grades, Guchi has aX of 60 and SX = 20. Pluto has aX of 60 and SX = 5.
(a) Who is the more inconsistent student, and why?
(b) Who is more accurately described as a 60 student, and why?
(c) For which student can you more accurately predict the next test score, and why?
(d) Who is more likely to do either extremely well or extremely poorly on the next exam?
