According to an article in Newsweek, the natural ratio of girls to boys is 100:108. In Turkey, the birth ratio is 100: 118 (45.8% girls). Suppose you do not believe the reported figures of the percent of girls born in Turkey. You conduct a study. In this study, you count the number of girls and boys born in 140 randomly chosen recent births. There are 50 girls and 90 boys born of the 140. Based on your study, do you believe that the percent of girls born in Turkey is 45.8?

A story describing a burger taste test among non-vegetarians was read by 352 high school students. To investigate the effect of the type of burger (veggie or meat) on subject's opinion of whether or not the burger tasted good, each burger had labels of veggie burger, beef burger, or a burger with no label. Each person was asked whether the burger tasted was good or not. Data are given in the accompanying table. Is there evidence that the proportion who believe that the burger tasted good for the three different labels differ? Test the relevant hypotheses using ? = 0.01. (Round your answer to two decimal places.)

There are 435 seats in a nation's House of Representatives. The number of representatives per state is calculated using a statistical formula determined by law, but allocation is roughly proportionate to population. In 2010, the nation's population was estimated to be 309.1 million. The state's population was estimated at 26.1 million. How many representatives would you expect to be assigned to the state? Suppose the state actually has 34 representatives. Compare this with the expected number of representatives from the state.
