Carry out a suitable hypothesis test at a 5% level of significance to test
1. Section 1: Introduction
a. Give a brief introduction about the assignment and search related article and write a paragraph of summary which supports your assignment. You need to give the full citation of the article.
b. Dataset 1: Give a short description about this dataset. Is this primary or secondary data? What are types of variables involved? Explain briefly what are the possible cases used in this study. c. Dataset 2: Explain how you collect the data and discuss its limitation (e.g. whether your sample is biased). Is this primary or secondary data? What is/are the type(s) of variable(s) involved? Give a description of cases you consider for this data set.
2. Section 2: Analysis of single variable in Dataset 1
a. To answer research question “Which type of public transport was most used by the NSW people during 8th to 14th of August 2016?”, provide a suitable numerical summary and graphical display for the variables mode of Dataset 1. Give a detailed comment to answer the research question.
Hints:
1. use pivot table to create a frequency table
2. use the frequency table to create pie chart or bar chart
3. See tutorial 2, Question 4a
b. Now to answer research question “Are there more than 50% of public transport users in NSW use the particular mode of transport found in Part a?” setup an appropriate hypotheses, perform hypotheses test and answer the research question by writing the conclusion of the test.
Do step-by-step hypothesis test
3. Section 3:
Analysis of two variables in Dataset 1 NSW Government need to decide on whether they have to build an underground Railway line from either Parramatta, Bankstown or Gosford to central. To prepare a recommendation for this;
a. Give a numerical summary and an appropriate graphical display for the variables location, by only considering those three stations; and the variable count by considering the data with trains only.
Hints:
1. Use Excel to filter location (select only 3 stations)
2. Use Excel to filter mode (select trains only)
3. Use Statkey with 2 variables (columns) : location & count
b. Perform a suitable hypothesis test at a 5% level of significance to test whether there is difference between mean counts of taps on and off.
Hints:
1. Use Statkey: “ANOVA for Difference in Means” (edit data and enter the values from columns tap and count. You can click ANOVA Table, record important values.
2. Use Statkey to find p-values (Theoretical Distributions: F)
3. Do step-by-step ANOVA test
c. Use the conclusion of the test in part b and the outputs in part a to write a recommendation to NSW government.
4. Section 4: Collect and analysis Dataset2
You are interested in finding whether there is a difference in preference between different gender in terms of their transport mode (Bus, Train, Ferry and Light Rail). by considering appropriate number of cases and variable, give a proper graphical display and use it to write a comments.
Hints:
1. Do survey
Section 5: Discussion & Conclusion Write an executive summary by combining all your findings in the previous sections which must be a valuable recommendation for NSW Transport. Give a suggestion for further research
