University of Central Florida School of Electrical Engineering and Computer Science EGN-3420 - Engineering Analysis. Fall 2009 - dcm Project 3 due Thursday week 12 (100 points) This project covers statistical characterization and linear regression. The material required for this project can be found in Chapters 14 and 15 of the textbook. Task 1 (40 points). Consider a discrete random variable X with probability density function p X ( x ). Deﬁne the following quantities: (1) mean; (2) median; (3) mode; (4) range; (5) stan- dard deviation; (6) variance; (7) coeﬃcient of variation. Assume now that X is a continuous random variable; provide the expressions for quantities (1)-(7). Consider the following set of data: 28.65 26.55 26.65 27.65 27.35 28.35 26.85 28.65 29.65 27.85 27.05 28.25 28.85 26.75 27.65 28.45 28.65 28.45 31.65 26.35 27.75 29.25 27.65 28.65 27.65 28.55 27.65 27.25 Sort the data, place it in 10 bins, and plot the histogram of the data. Use Matlab functions to compute the : (1) sample mean; (2) sample median; (3) mode; (4)
