Answer : C
Explanation
Step 1:
Heights of given bars 14, 15, 16 and 19.
Step 2:
Mean height = $\frac{(14 + 15 + 16 + 19)}{4} = \frac{64}{4}$ = 16
So height of new bar = 16
Answer : A
Explanation
Step 1:
Heights of given bars 14, 16, 18 and 22
Step 2:
Mean height = $\frac{(14 + 16 + 18 + 22)}{4} = \frac{70}{4}$ = 17.5
So height of new bar = 17.5
Answer : B
Explanation
Step 1:
Heights of given bars 10, 14, 16 and 18
Step 2:
Mean height = $\frac{(10 + 14 + 16 + 18)}{4} = \frac{58}{4}$ = 14.5
So height of new bar = 14.5
Answer : D
Explanation
Step 1:
Heights of given bars 9, 13, 15 and 17
Step 2:
Mean height = $\frac{(9 + 13 + 15 + 17)}{4} = \frac{54}{4}$ = 13.5
So height of new bar = 13.5
Answer : C
Explanation
Step 1:
Heights of given bars 11, 14, 15 and 16
Step 2:
Mean height = $\frac{(11 + 14 + 15 + 16)}{4} = \frac{56}{4}$ = 14
So height of new bar = 14
Answer : A
Explanation
Step 1:
Heights of given bars 9, 12, 13 and 14
Step 2:
Mean height = $\frac{(9 + 12 + 13 + 14)}{4} = \frac{48}{4}$ = 12
So height of new bar = 12
Answer : B
Explanation
Step 1:
Heights of given bars 15, 16, 17 and 20
Step 2:
Mean height = $\frac{(15 + 16 + 17 + 20)}{4} = \frac{68}{4}$ = 17
So height of new bar = 17
Answer : D
Explanation
Step 1:
Heights of given bars 13, 15, 17 and 21
Step 2:
Mean height = $\frac{(13 + 15 + 17 + 21)}{4} = \frac{66}{4}$ = 16.5
So height of new bar = 16.5
Answer : C
Explanation
Step 1:
Heights of given bars 15, 17, 19 and 23
Step 2:
Mean height = $\frac{(15 + 17 + 19 + 23)}{4} = \frac{74}{4}$ = 18.5
So height of new bar = 18.5
Answer : A
Explanation
Step 1:
Heights of given bars 10, 13, 14 and 15
Step 2:
Mean height = $\frac{(10 + 13 + 14 + 15)}{4} = \frac{52}{4}$ = 13
So height of new bar = 13
