1)Calculate all 4 business moments using pen and paper for the below data set? Solution: Business Moment 1: Mean(`mu`) = 1.4 Business Moment 2: Variance = 1.84, SD = 1.356 Business Moment 3: Skewness(sk) = 0.5727 Business Moment 4: Kurtosis(kt) = - 0.9542   2)What is the significance of expected value when simple…

A car has a weight of 1900 lb front axle and 1552 lb on the rear with a wheelbase of 100.6 inches. The tires have the following cornering stiffness values Given Date:- mf=1900lbs mr=1552lbs l=1006.6in wf=8452.7865N wr=6904.591N l=2.555m 1. Ackermann steer angles for 500, 200 and 50 ft radius ackermann steer angle = l/R*(180/3.14)+(k*ay)…
