Tomorrow we'll wrap up our notes on chapter 22, then do some practice tomorrow and Thursday!
HomeworK: Chapter 22 Quiz B
In 2000, the United Nations claimed that there was a higher rate of
illiteracy in men than in women from the country of Qatar. A humanitarian organization
went to Qatar to conduct a random sample. The results showed that 45 out of 234
men and 42 out of 251 women were classified as illiterate on the same
measurement test.
1.
Do the samples above provide evidence that the
United Nations’ claim was correct—that there was a higher illiteracy rate in
men than in women (in Qatar)? Test an appropriate hypothesis and state your
conclusion.
2.
Show the appropriate mathematics and calculate a
95% confidence interval for the difference in proportions of illiteracy in men
and women from Qatar. Then, interpret your interval.
