Alex believes the honor roll students at his school have an unfair advantage in being assigned to the science class they request. He asked 500 students at his school the following questions: "Are you on the honor roll?" and "Did you get the science class you requested?" The results are shown in the table below:
Help Alex determine if all students at his school have an equal opportunity to get into the science class they requested. Show your work, and explain your process for determining the fairness of the class assignment process.
The sports section of the East Mule Shoe Gazette runs a weekly question that readers can answer online. After the local university’s football squad was beaten by its rival for the forty-second straight season, the question was “Do you think that the coach needs to go?” Of the 182 people who responded, 89 percent said Yes. When people say that the newspaper poll is biased, they mean that:
A) students may have different opinions than townspeople
B)Repeated polls would give results that are very different from each other
C)Repeated polls would miss the truth about the population in the same direction

Suppose the government is considering the provision of traffic lights at three different locations, denoted 1, 2 and ach
traffic light costs $600 to install. There are three individuals (A, B, and C). If a traffic light is installed all individuals will
be taxed equally to pay for the costs and this information is known to the individuals. The decision whether to install
each individual traffic light is taken on the basis of a majority vote; and, for each individual, if the individual's valuation
is greater than or equal to the cost to them then they would vote in favour of provision. The table below gives the
value that each individual places on installing a traffic light at each of the locations:
