Mean: 7.4570 StDev: 0.4100 SE mean: 0.0941 90% confidence Interval (7.2939, 7.6201)
What is the margin of error for the confidence interval? Why does the margin of error increase with the confidence level?
Explanation / Answer
Margin of error = 7.457 - 7.2939 = 0.1631
Margin of error = Z * / sqrt(n)
As confidence level increases, Z value will also increase. If Z value will increase, then margin of error will also increase.
