To find the new sample mean and sample standard deviation, these values obtained in (a) will need to be multiplied by 62.43, so the new sample mean is 340.11 and the new sample standard deviation is 13.79. (Note: (1 g/cm’) (0.001 kg/g) (2.2046 Ib/kg) (30.48% cm3/ft3) = 62.43 Ib/ft3) This document was created with Win2PDF available at http://www.daneprairie.com.
