Calculate the coefficient of variation of the dataset. 1) 444.472 2) -73.567 3) 11.227 4) 84.793 5) 0.071 average speed of the cars was 70.5 and the standard devilation was 4.86. However, since th radar gun was biased. 4 is added to every observation in the dataset. What will the new mean Question 8 (1 point) Suppose that a police officer measured the speed of cars on a highway for an hour. The

Answer 1

7)

from above coefficient of variation =(std deviation/mean)*100 =(5.61/79.18)=0.071

8)

new mean =70.5+4=74.5
