Test the null hypothesis of equal means for the data given in given Problem using σ = .01.

Problem
Bacterial colonies were counted on 12 plates. There were two observers, and the plate counts obtained were as follows:

Plate Number	Observer 1	Observer 2	Observer 3
1	139	191	-52
2	121	181	-60
3	49	67	-18
4	163	143	20
5	191	234	-43
6	61	80	-19
7	179	250	-71
8	218	239	-21
9	297	289	8
10	165	201	-36
11	91	80	11
12	92	99	-7

Give a 99% confidence interval for the difference between the mean plate counts of the two observers. Do you believe that there is a difference? Why?
