I think I’ve encountered a few problems in this newest homework on what I believe is question 3. For part D it asks for the IQR which I know to be the difference between the first and third quartile. The correct graph above shows that the third is marked at 244 and the first is marked at 132, the difference between which is 112. However the program says the the difference is 32. Seeing as the standard deviation is 28 thats not possible. as well in part E, the section of the graph which contains the 15% with the highest cholesterol begins at 216mg/dl, but it says that that is also incorrect.

as well, problem two asks how many runs receivers 2 standard deviations under the mean get. Well the mean is 477 and the standard deviation is 376, so 2 standard deviations would leave you with negative runs which are not represented because I don’t think that is possible
