2. the standard deviation of Ybar
3. the probability that Ybar will be greater than 235 pounds
4. the probability that the weight of a single randomly selected college football player will be greater than 235 pounds

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
