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.)
Can someone please help? Thank you.
An additional data value is added to a dataset. The new value is far below the rest of the data. The standard deviation will decrease when this new value is added into the dataset.
