  4. Objective of STA 2023 Gen Ed Assessment • Assess student learning outcomesat the end of the semester. • Evaluate aggregate student artifacts for purposes of program improvement, analyzing exam results, etc. • Evaluation involves faculty teamsacross the program/discipline.

  5. Process & Objective of Assessment Day Prepare June We are here • Refine rubrics • Refine question Execute Fall Semester Present Assessment Day • Coordinate • Implement question • Turn in artifacts • Present results • Update Xitracs Analyze Spring Semester • Score artifacts • Perform data analysis

  6. Near-term Chronology • Jan 19: • Scoring Session conducted at Lake Nona () • Feb 9: • Evaluations returned to Jon & Mary • Mar - Apr: • Data analysis • Data presentation preparation • May 5 (Assessment Day): • Presentation of results • May - Jun: • Update Xitracs • June 8 @ 0930: Question & Rubric Refinement Session (Lake Nona)

  8. Question & Rubrics

  9. STA2023 Common Final Exam Question (Fall 2017) The manufacturer of a new hybrid sports utility vehicle (SUV) states that it gets an average of 48 miles per gallon (mpg) on the highway. A consumer group suspects that perhaps the new SUV’s gas efficiency is lower than the manufacturer’s statement. Assume that the gas efficiency of the SUV is approximately normally distributed. The consumer group randomly tests 13 of the new SUV’s under similar highway conditions and obtains the following results: 39, 40, 41, 42, 43, 43, 44, 45, 45, 46, 47, 47, 50

  10. STA2023 Common Final Exam Question (Fall 2017) 1a) Write the hypotheses statements symbolically below to test the consumer group’s claim: • H0: • Ha: 1b) Which hypothesis represents the consumer group’s claim? • (Circle one: Null Hypothesis (H0) or Alternative Hypothesis (Ha)

  11. STA2023 Common Final Exam Question (Fall 2017) 2) Explain what type of hypothesis testing you will perform and whether conditions are met. • Test this hypothesis using a significance level of α = 5%. (SHOW WORK!) • Clearly label a sketch with appropriate shading and calculate the test statistic (show formula and work).

  12. STA2023 Common Final Exam Question (Fall 2017) 3b) Would you reject or fail to reject the null hypothesis? • (Circle one: Reject H0 or Fail to Reject H0) • Explain your choice:_________________________ 4a) Using a significance level of α = 5%, write a conclusion in the context of this problem: 4b) A friend is looking for an SUV that averages 48 mpg or more on the highway. Would you advise your friend to purchase this new model SUV? • (Circle one: YES or NO)
