Heights of women have a bell-shaped distribution with a mean of 161 cm and a standard deviation of 6 cm. Using Chebyshev's theorem, what do we know about the percentage of women with heights that are within 2 standard deviations of the mean? What are the minimum and maximum heights that are within 2 standard deviations of the mean? At least % of women have heights within 2 standard deviations of 161 cm. (Round to the nearest percent as needed.) cm. The minimum height that is within 2 standard deviations of the mean is cm. The maximum height that is within 2 standard deviations of the mean is
