The confidence interval lower limit and upper limit for a population mean are (16.3, 19.5). What is the sample mean and the margin of error for the sample.A sample of size 73 with ¯xx¯ = 17.9 and ss = 6.7 is used to estimate a population mean μμ. Find the 95% confidence interval for μμ.

Sample mean =


Margin of error =
