Get range for categories
Suppose you have the following table:
(the ranges' frequencies are similar, but their sizes are not)
Now imagine that you are given the information that for a group of people, the mean category is 0.3 and the variance is 0.5. How can I find out the range of ages to which this data corresponds?
Unparseable latex formula:
[br]\begin{tabular}{|c|c|c|}[br]\hline [br]Age & Category & Frequency\tabularnewline[br]\hline [br]\hline [br]0-10 & 1 & 9\tabularnewline[br]\hline [br]11-20 & 2 & 10\tabularnewline[br]\hline [br]21-50 & 3 & 8\tabularnewline[br]\hline [br]\end{tabular}
(the ranges' frequencies are similar, but their sizes are not)
Now imagine that you are given the information that for a group of people, the mean category is 0.3 and the variance is 0.5. How can I find out the range of ages to which this data corresponds?
