A researcher is interested in examining whether there is a relationship between gender and political
party affiliation. Specificaly, they want to know if the pattern of political affiliation is the same for
men and women. The researcher collects data from a total of 52 participants: 26 women and 26
men. The researcher asks each participant whether they voted for the Democratic or Republican
candidate in the previous presidential election. The researcher expects that there will be an equal
proportion of participants voting for the democratic candidate and the republican candidate among
men and women. The researcher finds the following frequencies:

Among students at a nearby college, the proportion who say they're interested in their congressional district's election results has traditionally been 60%. After
a series of lackluster debates on campus, a political scientist claims that the proportion, p, of students at the college who say they're interested in their district's
election results is now less than 60%. A poll is commissioned, and 139 out of a random sample of 240 students at the college say they're interested in their
district's election results. Is there enough evidence to support the political scientist's claim at the 0.05 level of significance?

Airline B claim that they have 50% of the business with the remaining percentage shared equally amongst airlines A and C, i.e. 25% each.

The residents of the estate buy fuel at the two stations on a monthly basis. A recent survey found that the customers were not totally loyal to either petrol station and that they were willing to change as a result of advertising, service, and other factors. It was established that if a customer bought fuel from Mafuta in any given month, there was only a 60% chance that the customer would buy from Mafuta the next month and a 40% likelihood that the customer would buy fuel from Petroli the next month. Likewise, if a customer traded with Petroli in a given month, there was an 80% that the customer would buy fuel from Petroli in the next month and a 20% likelihood that the customer would purchase gasoline from Mafuta.
