QUESTION:
Determine the point estimate of the population proportion, the margin of error for each confidence interval, and the number of individuals in the sample with the specified characteristic, x, for the sample size provided.
Lower bound: 0.201, upper bound: 0.249, n = 1200
ANSWER:
Step 1 of 2
Given, Lower bound = 0.201, Upper bound = 0.249 and n = 1200
The population proportion
P = x/n
Where, p = (0.201+0.249)/2
p = 0.225
