Lab 3: Kissing the Right Way?
Background: Most people are right-handed and even the right eye is dominant for most people. Researchers have long believed that late-stage human embryos tend to turn their heads to the right. German biopsychologist Onur Güntürkün (Nature, 2003) conjectured that this tendency to turn to the right manifests itself in other ways as well, so he studied kissing couples to see whether both people tended to lean to their right more often than to their left (and if so, how strong the tendency is). He and his researchers observed couples from age 13 to 70 in public places such as airports, train stations, beaches, and parks in the United States, Germany, and Turkey. They were careful not to include couples who were holding objects such as luggage that might have affected which direction they turned. We will assume these couples are representative of the overall decision making process when kissing.
Goals:
- To set up and analyze a two-sided alternative hypothesis.
- To explore methods for developing a confidence interval for a process probability.
