2. In 2001, one country reported that, among 3132 white women who had babies, 94were multiple births. Therewere also 20 multiple births to 605 blackwomen. Does this indicate any racial difference in the likelihood of multiple births? a] Define the parameter and write the appropriate hypotheses. [PH] b] Checkthe assumptions and conditions and state the name of the test to be used. [AN] c] Find the test statistic [zscore] and the pyalue. [TU] d] State your conclusion in context. [MS] 3. In 2003 the Journal of the American Medical Association reported a study examining the possible impact of air pollution caused by the 9,!11 attack on New Yorlfs World Trade Center on the weight of babies. Researchersfound that 3% of 132 babies born to mothers who were exposed to heavy doses of soot and ash on September ill"h were classified as having low birth weight. Only 4% of 2312MBI babies born in another NYC hospital whose mothers had not been near the site of the disaster were similarly classified. 3] Does this indicate a possibility that air pollution might be linked to a significantly higher proportion of low weight babies? Test an appropriate hypothesis and state your conclusion in context. [PHANTDMS] b] If you concluded there is a difference, estimate that difference with a 9% confidence interval and interpret that interval in context. [ANIC] 4. Candidates for political office realize that different levels of support among men and women may be a crucial factor in determining the outcome of an election. One candidate finds that 52% of 423 men polled say they will 1rote for him, but only 45% of the 522 women in the poll express support. a] Is there really a gender gap? Complete a fully hypothesis test to test this information. b] How large is the gender gap?With which gender more in favor for this candidate? Create a 95% confidence interval to determine how large
