Okay, so in this one, we have ran a random sample of people in a large city and found that 120 out of 250 men would vote for donald trump, and 132 out of 240 women intended to vote for donald trump.
00:17
And then what we've done is we've ran a competence interval of the difference in those proportions.
00:22
And this is what we have here.
00:25
So it's based upon the interval is they're convincing evidence to support the claim that a greater proportion of women than men intended to, to vote for trump.
00:33
And the answer here is that no, there is not convincing evidence of a difference in those proportions.
00:48
And the reason why is because our interval does contain zero.
00:57
So zero is contained in our interval.
01:01
Remember that a confidence interval, in this case, these are the plausible values with 95 % confidence of what the difference in the proportion of men and women are.
01:11
And one of those that's contained in this interval is zero...
