Q: Height of women have a bell shaped distribution with a mean of 157 cm and standard deviation 7 cm. Using Chebyshev's theorem, what do we know about the percentage of women with heights that are within 2 standards deviations of the mean? What are the minimum and maximum heights that are within 2 standard deviations of the mean?
A: Atleast __% of women have heights within 2 standard deviations of 157 cm. (Round to the nearest percentage as needed)
The minimum height that is within 2 standard deviation of the mean is __ cm?
The maximum height that is within 2 standard deviation of the mean is __ cm?
