Chapter 4: Activity #5 - Standard Deviation and Passing Statistics Assume that you are deciding which professor to take for an Introductory Statistics course. There are two faculty who teach Introduction to Statistics at State College University. Dr. Dread has a relatively low score on Rate Your Professor and Dr. Stats- Pass has a relatively high score on Rate Your Professor. You are somewhat skeptical of online rating sites so you decide to do some research on your own. Below are the student passing rates over 9 years for both professors. Using data below: 1. Calculate the average number of students who pass Introductory Statistics for Dr. Dread and for Dr. Stats-Pass. 2. Calculate the standard deviation for the number of students who pass for each instructor. Student Passing Rate Year Dr. Dread Dr. Stats -Pass 2017 45 50 2016 44 45 2015 45 35 2014 44 50 2013 42 35 2012 40 30 2011 45 35 2010 42 30 2009 40 50
