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 17 with a mean of 17.6 and a standard deviation of 12.2 at a confidence level of 99.8%. Report M.E. accurate to one decimal place because the sample statistics are presented with this accuracy.

Step 1
We have a sample size (n) of 17, a sample mean (\(\bar{x}\)) of 17.6, and a sample standard deviation (s) of 12.2. We are asked to find the margin of error (M.E.) for a 99.8% confidence level. Show more…

Assume that a sample is used to estimate a population mean μ. Find the margin of error M.E. that corresponds to a sample of size 6 with a mean of 78.6 and a standard deviation of 20.4 at a confidence level of 98%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Assume that a sample is used to estimate a population mean μμ. Find the margin of error M.E. that corresponds to a sample of size 17 with a mean of 47.9 and a standard deviation of 15.4 at a confidence level of 95%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
