A researcher wants to see if birds that build larger nests lay larger eggs. Over the course of the year, she collects data by randomly checking different trees in forest preserves across the US. Conduct a hypothesis test at the 5% alpha level to see if large nests have a larger mean nest than other nests. The data is summarized below: Large nests: n=60 mean(gm)=38.2 SD(gm)=4.9

Other nests: n=159 mean(gm) 37.5 SD(gm)=6.4
