2. Four parties contested an election held two years ago. Conservatives captured 29% of the vote, liberals 41% of the vote, while the greens and the extreme right parties split the rest among themselves equally. A survey of 1500 voters this year yielded the following: 410 conservatives, 590 liberals, 270 greens, and 230 went to the extreme right party. Has the voter support changed since the elections? Test at the 10% level of significance. (a) If the voter support has not changed, what is the expected number of voters for each party? (b) Write down the hypotheses for this test. (c) Perform the test in question.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
