Textbook Question
Chapter 4, Problem 4.25P
During the course of a motor test, the motor rpm (revolutions per minute) is measured and recorded at regular intervals as
990
1030
950
1050
1000
980
Calculate the mean value, standard deviation, and best estimate of true value for this data set. Over what interval would 50% of the entire population of motor speed values fall? Test the data set for potential outliers.
