Transcribed Image Text:Assignment #6
For this assignment, you will be using the Tips Dataset file in
Excel.
The file contains both qualitative and quantitative variables.
Choose two qualitative variables. You will be using a hypothesis
test to determine if the two variables are associated.
1. Which two variables did you choose? Create a table to
summarize the data from the data file. Example below:
Example: Listed below are data from a survey conducted
recently where Males and Females responded to their happiness
with their supervisor (this is fictitious data).
Response Male Female Total
Not at all
23
25
48
Somewhat
13
22
35
Very
Total
26
16
42
62
63 125
2. Which hypothesis test is appropriate for this type of data?
Explain. What is your null hypothesis? What is your
alternative hypothesis?
3. Conduct the hypothesis test. Include any output from Excel.
What is your test statistic? Using alpha = 0.05 determine
the results of your hypothesis test. Explain.
4. Interpret your results into a conclusion based on your
hypothesis (are the variables associated or not?). What are
the practical implications of your conclusion? Explain.
