Save The accompanying data contains the monthly retail sales ($millions) of a large country's women's clothing stores for 70 months. A sample taken from this population to estimate the average sales in this time period is shown below.

Calculate the population mean. The population mean is 2746.57 million dollars. (Round to two decimal places as needed.) b. Calculate the sample mean. The sample mean is 2750.8 million dollars. (Round to two decimal places as needed.) c. How much sampling error is present in this sample? The sampling error is 4.23 million dollars. 2,332 2,604 2,721 3,025 2,607 2,407 2,443 2,622 2,434 3,141 2,594 3,173 2,525 2,750 2,801 2,341 2,648 2,964 3,082 2,952 2,525 2,529 2,566 2,788 2,423 3,126 3,026 3,161 2,827 2,666 2,492 3,004 2,512 3,041 2,906 3,148 2,967 2,748 2,873 2,488 2,500 3,051 2,514 2,862 2,931 2,977 2,495 2,372 2,934 3,126 2,829 2,520 2,615 3,102 2,506 2,407 2,487 2,568 2,516 2,460 2,845 2,461 2,975 2,948 2,981 2,770 2,992 2,664 3,179 2,691 (Round to two decimal places as needed.) d.
