Homework:

1. Read in a file of numbers and add up the numbers in each line and
print that sum just below the line, e.g., given
a file foo


3 5 21 1.5
4.1 -3.2 8

you will print out:

3 5 21 1.5
30.5
4.1 -3.2 8
8.9

2. Enhance differencebetweenmeans_sig.py which I sent you a few weeks
ago to calculate the mean and standard deviation of the two original
populations.
(in our example placebo and drug).
So your standard deviation calculation will give two numbers, one for
placebo and one for drugs.
