A ribbon that is 100 centimeters long is being cut into pieces that are 4.5 centimeters each. Which of the following is the greatest number of whole pieces that can be created?

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
