Answer 1

Answer:

(a) A

Step-by-step explanation:

the answer is in the picture...

mean of x = 9.37

SD of x = 3.01

CV of x = 3.01/9.37 × 100

= 32.12

mean of y = 9.12

SD of y = 4.54

CV of y = 4.54/9.12 × 100

= 49.78

so CV x = 32.12 (less variable , more consistent)

CV y = 49.78 (more variable, less consistant)

there for Company A is more consistent
