Answer:
The sample size should be approximately 151.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 100
Population standard deviation, σ = 15
We have to evaluate the sample size, n.
Alpha, α = 0.10
Confidence interval:
Putting the values, we get,

Thus, the sample size should be approximately 151.
All you do is calculate the area of a whole big triangle
estimate
1 3/4 =2
base = 2(2) + 2(1) = 6
height = 2
A = 1/2(6)(2)
A = 12/2
A = 6
answer is A
6 m^2
