In our local town people are affiliated with one of 3 parties,
A, B and C. We would like to study if there is any correlation
between a person’s gender and political affiliation.
In the first part you are supposed to collect the data. Here we
will not ask to collect the data explicitly, but require you to
specify the data collection process, so you can make better
conclusion:
a) Specify how would you go about collecting the data. Make
sure to provide what data you want to collect, any format, the key
factors you want to keep in consideration, sample size and so on
(max 15 sentences)
Now that you have thought about the experiment and discussed the
process of data collection with your colleagues, they will help you
in getting the actual data collected so you can do the analysis.
The table below shows the data collected by your colleagues and
summarized for your analysis:
Now let us start the analysis:
b) How many people were sampled in total?
c) How many men and women were sampled?
d) Which party has the greatest number of representatives?
e) State your null hypothesis.
Based on the null hypothesis and the observed data, answer the
following questions:
f) (6 points): How many females are expected to be in party A, B, C
respectively?
g) (6 points): How many males are expected to be in party A, B, C
respectively?
h) (2 points): What is the test statistic you would use? Justify
(max 3 sentences)
i) (8 points): Calculate the value of the test statistic based on
the number you calculated above and the data you collected. Do not
use any R function that directly calculates the test statistic.
Show your work explicitly.
j) (5 points): What would you conclude based on the test statistic?
Justify (max 5 sentences)
