Question

Assume that a sample is used to estimate a population proportion p. Find the margin of error M.E. that corresponds to a sample of size 364 with 47% successes at a confidence level of 95%.

M.E. =       %

Expert Solution
Step 1

Proportion is almost similar to the concept of probability. Proportion is a fraction of population or sample which has a specific characteristic of interest.

Margin of error is the error due to random sampling. Margin of error reduces with increase in sample size.
