Three friends order a pizza for $14, a two-liter bottle of soda for $2.75 and bag of chips for $2.15 They want to evenly split the total cost. Determine how much each person owes.

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
