Answer:
a) 38
Step-by-step explanation:
The normal distribution can be applied if:
and
In this question:
Then
a) 38
n = 38.
Then
38*0.27 = 10.26
38*0.73 = 27.74
Satisfies. But is this the smallest sample of the options which satisfies.
b) 14
n = 14
Then
14*0.23 = 3.22
14*0.77 = 10.78
Does not satisfy
c) 10
Smaller than 14, which also does not satisfy, so 10 does not satisfy.
d) 48
Greater than 38, which already satisfies. So the answer is a)
ANSWER
EXPLANATION
We have that the shaded sector is subtended at 210 degrees at the center of the circle that has a radius of 12 inches.
The area of a sector is given as:
where A = angle the sector subtends at the circle's center
So, we have that:
That is the answer.
