Data Analysis Assignment #3
Spring 2017
STAT 250
Your submitted document should include the following items. Points will be deducted if the following are
not included:
1. Type your Name, STAT 250 with your correct section number (e.g. STAT 250-xxx) and Data
Analysis Assignment #3 centered on the top of page 1 of your document.
2. Number your pages across your entire solutions document.
3. Your document should include the ANSWERS ONLY to the following FOUR questions with
each answer labeled by its corresponding number and subpart. Keep the questions in order. Do
NOT include the questions in your submitted document.
4. Generate all requested graphs and tables using StatCrunch.
5. Upload your document onto Blackboard as a Word or pdf document using the link provided by
your instructor.
Elements of good technical writing:
Use complete and coherent sentences to answer the questions.
Graphs must be appropriately titled and should refer to the context of the question.
Graphical displays must include labels with units if appropriate for each axis.
Units should always be included when referring to numerical values.
When making a comparison you must use comparative language, such as “greater than”, “less than”, or
“about the same as.”
Ensure that all graphs and tables appear on one page and are not split across two pages.
Show all mathematical calculations when directed to compute an answer ‘by-hand.’
When writing mathematical expressions into your document you may use either an equation editor or
common shortcuts such as:
x can be written as sqrt(x), p̂ can be written as p-hat, x can be written as
x-bar.
