Answer:
a) 1.8
b) 11.8
c) 23.6
mean: sum of numbers/total numbers
<h3 /><h3>Part A</h3>
⇒ mean: (2.4+1.6+3.2+0.3+1.6)/5 ⇒ 9/5 ⇒ <u>1.8</u>
<h3>Part B</h3>
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 ⇒ <u>11.8</u>
<h3>Part C</h3>
if the new data doubled, the mean will be double
11.8 * 2 = <u>23.6</u>
