The best way to solve this problem is using excel.
00:06
First, we need to build this table with the given information into the problem.
00:11
This, the columns represent the given treatments on the problem because look, the problem is talking about an experimental results.
00:22
We have different treatments, so a, b, and c are different treatments.
00:28
And then we have different responses, as different variations on the treatments.
00:34
So we build this table.
00:36
This is called a two -way table.
00:40
Then the total columns and rows, we just simply add them all.
00:44
So this is 27 is because we added all of these rows.
00:47
So 10 plus 9 plus 8, and the 68 is 10 plus 12 plus 8 plus 20 plus 8.
00:52
Make sure that we did a good job because when we add the total of the rows must equal the total of the columns.
01:00
So 27 plus 23 plus 47 plus 56 plus 23 is equal to 176.
01:07
68 plus 55 plus 53 is equal to 178...
