Data show that men between the ages of 20 and 29 in a general population have a mean height of 69.3 inches, with a standard deviation of 3.1 inches. A baseball analyst wonders whether the standard deviation of heights of major-league baseball players is less than 3.1 inches. The heights (in inches) of 20 randomly selected players are shown in the table. E Click the icon to view the data table. Test the notion at the a= 0.01 level of significance. What are the correct hypotheses for this test? The null hypothesis is Ho: V3.1. The alternative hypothesis is H,: 3.1.

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.)
