Find the margin of error for a 90% confidence interval when the standard deviation is LaTeX: \sigma= 50=50 and LaTeX: n = 25=25. (Round to three decimal places.)

The margin of error  for a 90% confidence interval is 16.4

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 25

Standard deviation = 50

Margin of error =

Putting the values, we get,

Thus, the margin of error  for a 90% confidence interval is 16.4
