Given: ac and db are diameters. m∠3=

Evaluate-27 ^4/3/8 a) - 81/16 b) 81/16 c) 16/81

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed
