At least (1-(1/3)^2)% = 89% of the data is within 3 std of the mean ....... ( The rest is not really needed) Minimum is 159-3*6 = 141 cm , maximum is 159 + 3*6 = 177 cm .At least 89 % of women have heights within 33 standard deviations of 159 cm. (Round to the nearest percent as needed.) The minimum height that is within 33 standard deviations of the mean is 141 cm. The maximum height that is within 33 standard deviations of the mean is 177 cm. ( This might help.)
