2. According to Chebyshev’s theorem, at least ________, of the lifetimes lie between 656 hrs and 1028 hrs.
a. 56% b. 75% c. 84% d. 89%
3. Suppose that the distribution is bell shaped. According to the empirical rule approximately _________ of the lifetimes lie between 656 hrs. and 1028 hrs.?
a. 68% b. 75% c. 95% d. 99.7%
4. Suppose that the distribution is bell shaped. According to the empirical rule
approximately 99.7% of the life times lie between ______ hours and _______ hours?
See attached file for full problem description.
The solution gives the details of calculation of probability based on Chebyshev’s inequality. Probability based on empirical rule is also discussed.
