Using Excel, analyse quantitative data that are available from the Learning Hub in the As-
signment section. You will submit two files, an Excel file and a Word file containing a basic
report to accompany the Excel file. The analysis should cover the following elements:
Part A. In Excel, complete the missing columns in the “Raw Data” sheet. In the report
just state, in clear language, the total sales revenue for the last 36 months.
Part B. Find the number of rows for each source country. Also for at least 3 of the coun-
tries with the highest sales revenue in the last 36 months show a breakdown of
descriptive statistics (mean, median, standard deviation, etc.) for at least 3 of the
numerical variables (columns with continuous data, including monetary values)
for that country. Place this analysis into a worksheet titled “Part B Group [Group
number]”. Use your group’s name or number in place of [Group number]. Note:

help.
Part C. In a separate worksheet titled “Charts and Graphs Group [Group number]”, find
the frequencies (number of rows) for each Stock Type. From this data produce
the following for the report:
a. Pie chart,
b. Pareto chart
c. Also, choose two continuous variables and produce a scatter plot of one vari-
able against another. In the same worksheet find the correlation coefficient,
r, of the relationship between the variables. Place this in a worksheet called
“Scatter Plot”. In the report, discuss the implications of the correlation value.
Any other charts or graphs that are used in the report should be placed in a
worksheet titled “Report Charts and Graphs”.
Part D. Choose two stock types (preferably with relatively high frequencies). Choose any
of the columns containing numerical data. Make a worksheet titled “Mean dif-
ference test Sem 2”. Add a table with just the data selected. In the same work-
sheet, perform an appropriate test to see if there is a significant difference be-
tween the mean values of the variables for the two stock types. In the report
state the assumptions and conditions of the experiment, including ? level. Also,
in the report clearly show the six steps of the test. Make sure you state your test
decision carefully, and very briefly state the business conclusion. Use graphs to
help (box and whisker plot may help here).
Part E. Suppose that in a previous analysis, performed some years ago, the mean and
standard deviation for the “Sales last 36 months (units)” variable were known to
be,
3,450
? = 5,23.3代写data in Excel
Has there been a significant change in the mean for this variable? Perform an ap-
propriate hypothesis test on this claim. Show your Excel working in a sheet titled
“Inference 2016 S1”. Show full, six-step working in the report (including state-
ment of assumptions).
Also perform a basic test of normality on the data in Excel and discuss in the re-
port.
