Answer:
1.8 ; 11.8 ; 4.18
Step-by-step explanation:
Given the data:
X : 2.4,1.6, 3.2,0.3, 1.5
Mean, m = Σx / n
Σx = 9 ; n = 5
m = 9 /5
m = 1.8
If data is increased by 10:
X : 12.4, 11.6, 13.2, 10.3, 11.5
Σx = 59 ; n = 5
m = 59 /5
m = 11.8
If data values is doubled :
X : 5.76, 2.56, 10.24, 0.09, 2.25
Σx = 20.9 ; n = 5
m = 20.9 /5
m = 4.18
