So our question says among 2 ,739 female atomic bomb survivors, 1 ,397 developed thyroid disease.
00:09
Among 1 ,352 male atomic bomb survivors, 436 developed thyroid disease.
00:16
Now we are supposed to use a 0 .01 significance level to test the claim that the female survivors and the male survivors have different rate of thyroid diseases.
00:26
So i kind of grouped the data sets for female and male into two different samples.
00:32
For female we have sample one and for male we have sample two.
00:35
So for the female sample, our n is across to 2 ,739.
00:40
And the number of female that had the thyroid disease, there are 1 ,397.
00:44
And the proportion of female that had the thyroid disease, we have 1 ,397 divided by 2007.
00:51
And that gives us 0 .51...
