You want to determine the effect of soap on bacterial colonies. In order to make sure that the environment does not affect your experiment, you divide 12 different petri dishes in half - one side is exposed to soap, the other is a control. You measure the number of colonies that grow in each petri dish and come up with the following results:

petri dish; 1 2 3 4 5 6 7 8 9 10 11 12

soap; 10 5 7 10 19 11 13 17 19 8 11 10

control; 20 17 11 17 26 18 21 25 24 17 17 17

Perform a complete one sided hypothesis test (why?) to see if there is a difference in bacterial colonies between the soap and control dishes.

Again - notice that other than using a one sided test you are given no advice. You need to figure this out on your own, although this one should be a bit easier than
