How to use Subpopulation data?
Dear Helpers
I have a sample frame and i have sampled from it using three methods and now i want to calculate the statistics but i only get the population parameters.

I am sorry for asking this stupid question, but i have been running in circles. I want to randomly generate a scaling point of between 1 and 10, for say hundred entries, where the first 10% percent is has rates between 2 and 7, the next 15% 3 and 7, 20% between 3 and 9, 20% between 3 and 10, 35% between 5 and 10.

Dear All
let me go one step further by asking you if you could help me show that the distribution of this data in normal. have a little idea (by trial and error) but i seem to not fully understand how its done.

par(las=1)
hist(H, breaks=seq(40000, 60000, 1000), freq=F)

Highlighint rjs problem on a new product
Hi,
Problem Summary:
I have been trying to add the highlight effect to my table but
everytime a new record is added the highlighting gives an rjs error.
However when i click the add to cart button on a product that already
exists inside the table, the highlight effect works. Is this because
the partial must only have only one <tr></tr> in it and the <table>
must be on the other
