The margin of error for a sampling distribution is found as 3.34.
Explain the term margin of error?
- The margin of error, sometimes known as the confidence interval, provides information on how closely your survey results will likely reflect the opinions of the general community.
- Keep in mind that conducting surveys requires you to strike a balance by using a smaller group (the survey respondents) to represent a much broader one.
Margin of error = z × σ/√n
- n = sample size (36)
- σ = population standard deviation (12)
- z = z-score
Thus, put the values;
z-score for 93% confidence level = 1.67
Margin of error = 1.67 ×12/√36
Margin of error = 3.34
Thus, the margin of error for a sampling distribution is found as 3.34.
