In a random sample...

In a random sample of six microwave ovens, the mean repair cost was $85.00 and the standard deviation was $11.00. Assume the population is normally distributed and use a t-distribution to construct a 90% confidence interval for the population mean mu. What is the margin of error of mu? Interpret the results.
