The tutor prepares for a statistics experiment. The first step is to generate two lists: one random, one less so.

To generate fifteen random numbers with Perl one can use the following code:

for ($i=0;$i<15;$i++){ $num=sprintf("%.0f",100*rand()); print $num; print " "; }

To generate fifteen somewhat less random numbers, one can add 5 to each output:

for ($i=0;$i<15;$i++){ $num=sprintf("%.0f",100*rand()+5); print $num; print " "; }

My plan is to compare these two lists, using the matched-pairs t-test (see my post from yesterday), to find if it can determine a difference between them.
