Most people are right-handed, and even the right eye is dominant for most people. Molecular biologists have suggested that late-stage human embryos tend to turn their heads to the right. In a study reported in Nature (2003), German bio-psychologist OnurGntrkn conjectured that this tendency to turn to the right manifests itself in other ways as well, so he studied kissing couples to see which side they tended to lean their heads while kissing. He and his researchers observed kissing couples in public places such as airports, train stations, beaches, and parks. They were careful not to include couples who were holding objects such as luggage that might have affected which direction they turned. For each kissing couple observed, the researchers noted whether the couple leaned their heads to the right or to the left. They observed 124 couples, ages 13-70 years. Suppose that we want to use the data from this study to investigate whether kissing couples tend to lean their heads right more often than would happen by random chance. The null hypothesis is in the original study was H0: pi = 0.5; suppose our null hypothesis was h0: pi=0.60.

1. In the context of the null hypothesis, determin the standardized statistic form the data were 85 of 120 kissing couples leaned their heads right.

2. Select the best comparrison between this standardized statistic and the statistic based on a null hypothesis of pi=0.50
