Homework Help: Statistics

Posted by Amy on Wednesday, June 24, 2009 at 6:21pm.

Two problems:

1. Find D sub 3 of the following data set:
60, 40, 26, 33, 23, 53, 36, 23, 28, 12, 30, 47

2. Find P sub 26 of the following 25 scores:

38.5, 41.5, 52, 52.5, 61, 63, 63.5, 68, 69, 69, 78.5, 79, 80, 83, 87, 88.5, 88.5, 91, 91.5, 92, 92.5, 94, 94, 97, 97

I have a formula that says (X-mean)/standard deviation, but I'm not really sure if/how that helps here.

Help is greatly appreciated!
