Answer:

a) 1.8

b) 11.8

c) 23.6

mean: sum of numbers/total numbers

Part A

⇒ mean: (2.4+1.6+3.2+0.3+1.6)/5 ⇒ 9/5 ⇒  1.8

Part B

If all the data's are increased by 10

{12.4, 11.6, 13.2, 10.3, 11.5}

Then mean ⇒ (12.4+11.6+13.2+10.3+11.5)/5 ⇒ 11.8

Part C

if the new data doubled, the mean will be double

11.8 * 2 = 23.6
