Question

Assume that a sample is used to estimate a population mean. Find the margin of error (M.E.) that corresponds to a sample of size 6 with a mean of 63.5 and a standard deviation of 8.6 at a confidence level of 90%. Report M.E. accurate to one decimal place because the sample statistics are presented with this accuracy.

Step 1

To find the critical value for a 90% confidence level, we can use a z-table or a calculator. For a 90% confidence level, the critical value is approximately 1.645. Show more…
