Question Help A study was conducted on shoe sizes of students, reported in European sizes. For the men, the mean size was 45.84 with a standard deviation of 2.17. To convert European shoe sizes to U.S. sizes for men, use the equation shown below. USsize = EuroSize x0.7849 - 24.9 What is the mean men's shoe size for these responses in U.S. units? b) What is the standard deviation in U.S. units? a) The mean men's shoe size in U.S. units is (Round to two decimal places as needed.) b) The standard deviation in U.S. units is (Round to two decimal places as needed.)
Suppose you wish to determine if the mean IQ of students on a certain campus is different from the mean IQ in the general population, 100. To conduct this study, you obtain a simple random sample of 90 students on this campus, administer an IQ test, and record the results. The mean IQ of the sample of 90 students is found to be 106.5 with a standard deviation of 13.1. Complete parts (a) through (c) below. Question Help v Click the icon to view the t-distribution table.
