A swimming pool is 18' wide, 36' long, and 10' deep. Before anyone jumps into the pool, the water level is 8'. After your friends jump in, the water rises 3 inches. If the average person has a volume of 3 cubic feet, how many people must have jumped in the pool?

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
