The table represents a linear function. what is the slope of the function? –6 –4 4 6

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2

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
