Would the standard deviation for the males in the class be greater than 2.75 inches, exactly 2.75 inches, or less than 2.75 inches?

**bobpursley**, Saturday, January 15, 2011 at 9:30pmI think there is a problem here. What if there are 215 students in the stat class, 15 of which are males. The remaining 200 are female. For the statistics class, the females overwhelm the males, so the Class statistics largely reflect the females, and the males is just down in the noise. Now standard deviation: I dont see how any analysis can be done without making some assumptions about class size.
