Okay, and your question, you're told a number of young adults ages 19 to 25 live with their parents.
00:05
Data were collected, and the proportion of men and women in that age group who live with their parents was calculated.
00:12
A 90 % confidence interval for the difference in the sample proportions was found to be 0 .064 to 0 .110.
00:24
And the question is asking you, what is the value of the sample statistic that would be used to estimate, the difference in the proportion populations for men and women living with their parents.
00:36
Well, confidence intervals, let's just take a quick look at how they are made.
00:41
The formula is typically statistic, the statistic that we're looking for, plus or minus a margin of error.
00:52
So ultimately, you're looking for this value.
00:56
And that value would be the p hat of men minus p hat of women...
