Answer:
The reasonable range for the population mean is (61%, 75%).
Step-by-step explanation:
The interval estimate of a population parameter is an interval of values that consist of the values within which the true value of the parameter lies with a certain probability.
The mean of the sampling distribution of sample proportion is, .
One of the best interval estimate of population proportion is the 95% confidence interval for proportion,
Given:
n = 150
= 0.68
The critical value of <em>z</em> for 95% confidence level is:
Compute the 95% confidence interval for proportion as follows:
Thus, the reasonable range for the population mean is (61%, 75%).

Answer:
12+8pi in^2
Step-by-step explanation:
We have a semicircle with radius of 4
A = 1/2 pi r^2
A = 1/2 pi (4)^2
A = 1/2 (3.14) 16
A = 8pi
We also have a triangle with base (4+4) = 8 and a height 3
A = 1/2 bh
A = 1/2 (8)3
A = 12
Add them together
A = 12+8pi in^2
