BIG Corporation produces just about everything but is currently interested in the lifetimes of Its batteries. To investigate its new line of Ultra batteries, BIG randomly selects 1000 Ultra batteries and finds that they have a mean lifetime of 940 hours, with a standard deviation of 96 hours. Suppose that this mean and standard deviation apply to the population of all Ultra batteries. Complete the following statements about the distribution of lifetimes of all Ultra batteries. (a) According to Chebyshev's theorem, at least (Choose one) of the lifetimes lie between 748 hours and 1132 hours. (b) According to Chebyshev's theorem, at least 56% of the lifetimes lie between hours and hours. (Round your answer to the nearest whole number.)
