Answer:
solution is given below
Step-by-step explanation:
A simple random sample size n = 250 . Of the 250 employed individuals surveyed,42 responded that they did work at home at least once per week.
Construct 99% confidence interval for population
For proportion : 42 / 250 = 1/10 = 0.16
Mean = 2.5 * sqrt [ 0.1 * 0.9 / 250]
= 2.5 * 0.01
= 0.47
Construction of hypothesis:
0.10 - 0.047 < p < 0.10 + 0.047
Given:
Consider the given equation is
To find:
The values of x.
Solution:
We have,
Taking square root on both sides, we get
Adding 18 on both sides, we get
Now,
and 
and 
Therefore, the correct option is A.
