How Many Stars Are in the Sky?

As a child, have you ever tried to lay out and count all the stars in the night sky?  I used to do this a lot when we went camping.  I would usually end up falling asleep half way through the sky.  Now as an adult, I counted a couple stars in the sky and mathematically calculated the total number of stars in the night sky.  Below are my results....

The directions said to hold a toilet paper to your eye and count all the stars you see through the tube. I did this a total of 20 times at different parts of the sky. Below are my 20 observations...

                                                                   12         6
                                                                   10         10
                                                                   11         3
                                                                   4           5
                                                                   9           11
                                                                   5           12
                                                                   6           9
                                                                   11         6
                                                                   15         3
                                                                +  9          9
                             the total is                           166
                             the average is                      8.3

Next, I calculated the total number of stars in the sky by multiplying the average by 99.3.  The total I calculated was 6,840.78 stars.

So this is it!!! This is the answer to my childhood camping question!  Theoretically, there were 6,840.78 stars in the night sky the night of  June 21, 2013 at 10:30PM.
