center change.

Answer 1

Answer:

a)18.5  b)16  c)14

Step-by-step explanation:

a) Total number of classes: 12

9,12,13,14,14,14,18,19,22,22,23,42 (arrange in ascending  order)

mean=$\frac{Total numbers of cans}{Total numbers of classes}$= $\frac{(9+12+13+14+14+14+18+19+22+22+23+42)}{14}$=$\frac{222}{12}$=18.5

b) median=$\frac{14+18}{2}$=16

c) 9,12,13,14,14,14,18,19,22,22,23

The center will change to 14 as the total number of classes decrease by 1.
