3. In 2010, 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 tested reading ability in a random sample of Qataris. The results revealed that 45 out of 234 men and 42 out of 251 women were illiterate. Do these results indicate that the United Nations findings were correct? a. State your null and altemative hypotheses. b. If you pool the men and women together, what percent of the overall sample is illiterate? c. Calculate the standard error and draw and label the sampling distribution. d. Calculate a test statistic and P-value. e. Explain what your P-value means in this context. f. If a (alpha) = .1, what do you conclude?
