Question

A survey was conducted on a college campus to determine what type of food students want in the dining halls. Out of 1200 students that completed the survey, 45% said that they wanted ice cream available. What is the margin of sampling error for the survey?

a. 0.149
b. 0.029
c. 0.450
d. 0.214

Answer 1

The answer is b. 0.029

Explanation:

Margin error for a sample size of 1200 is 2.9%.

The Margin error formula can be represented as:

`z * \: \sqrt{ (p0(1 - po))/(n) }`

Where

z = critical value

n = sample size

`p0 = sample \: proportion`
