In a recent year, the SF Giants won 47 of 81 home games and they won 37 of 81 away games. Use a 0.05 significance level to test the claim that the proportion of wins for home games is greater than the proportion of wins for away games. Does there appear to be a home-field advantage?
In a winter of an epidemic ﬂu, the parents of 2000 babies were surveyed by researchers at a well-known pharmaceutical company to determine if the company’s new medicine was effective after two days. Among 120 babies who had the ﬂu and were given the medicine, 29 were cured within two days. Among 280 babies who had the ﬂu but were not given the medicine, 56 recovered within two days. Is there any signiﬁcant indication that supports the company’s claim of the effectiveness of the medicine? Use a significance level of 0.10
