For this question, the right answer is option 4.
00:10
Because we can see from, let's say, the first answer, for region or pay -wise, region levels differ from each other, significant with regards to survey responses.
00:19
Actually, this is mostly right, but for the region, and we see when we between sw minus and w, we have a p -value of 0 .96, which is much higher than 0 .05.
00:42
So it means that no evidence to say sw minus nw is not equal to 0.
00:54
This means that we support now hypothesis, which is sw minus the nw should be 0.
01:05
And we end up with a very big p value, so we have no evidence to reject, not hypothesis.
01:11
And similarly, for design, and then we have 3 minus 1 with pay value equal to 0 .87, which is much higher than 0 .05...
