So we're looking at the proportion of men and women on how they answer whether the responsibilities, household responsibilities are evenly distributed.
00:11
And we're going to assume that the proportions are equal for males and females, and alternately that the males have a higher proportion than females in their opinion.
00:20
And we're doing a 1 % significance test.
00:23
And so at 1%, if we look at having all 1 % in this upper tail, since it's a one -tail test, we would be rejecting the null if our test statistic is higher than this 2 .326, which is the value that has 1 % in the upper tail.
00:41
And so we have our two proportions from our male sample and our female sample, and we do need to have our pooled p in our test statistics.
00:51
So we pooled and add together our total number of people sampled of males and females and the total number of successes.
00:59
And so we can see that the two portions are, you know, we go about 5 .5 % apart.
01:05
And we're assuming they're both equal to this pooled p.
01:08
So let's calculate the test statistic.
01:11
And the test statistic is to take the difference in the two proportions divided by that standard error, which is our pooled p and times its complement divided by the sample size...
