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.)
A distribution of values is normal with a mean of 60 and a standard deviation of 7.Find the interval containing the middle-most 82% of scores: __________Enter your answer accurate to 1 decimal place using interval notation. Example: (2.1,5.6)Hint: To work this out, 1) sketch the distribution, 2) shade the middle 82% of the data, 3) label unkown data values on the horizontal axis just below the upper and lower ends of the shaded region, 4) calculate the percentage (area) to the left of the lowermost unknown data value, 5) calculate the TOTAL percentage (area) to the LEFT of the uppermost unknown data value, 6) use invnorm to calculate the lowermost data value, 7) use invnorm to calculate the uppermost data value. The data values you get from steps 6 and 7 are used to answer the question.
