In addition to being a great way to deliver output to someone else, this is also a great way to save your own hard copy. To try it out, simply click on the Mail link.
Technology project 3

a. Find the mean and standard deviation, and verify that the pulse rates have a distribution that is roughly normal.

the mean is 0 and the standard deviation is 1

b. Treating the unrounded values of the mean and standard deviation as parameters, and assuming that male pulse rates are normally distributed, find the pulse rate separating the lowest 2.5% and the pulse rate separating the highest 2.5%. These values could be helpful when physicians try to determine whether pulse rates are unusually low or unusually high.

Sum = 6.25 + 20.25 + 2.25 + 6.25 + 30.25 + 0.25 = 65.5 Divide by N-1: (1/5) × 65.5 = 13.1 s=√(13.1) = 3.619
