Study Notes from Class Discussion

Exams have been graded; they will be returned on Thursday.
The answer key for the exam will be posted either today or tomorrow.
Students who completed the WileyPLUS review and scored over 70% received extra credit points.
- This extra credit was granted to reward effort.
- Not completing the review will not negatively impact students' grades.

A written assignment will be distributed today.
- Students will complete this assignment during class.
- After completing the written assignment, students may watch a video related to the assignment’s topic.
The written assignment is due on Thursday of next week at the beginning of class.
- Due date emphasized for clarity.
- Some confusion with a previous due date mentioned in Canvas, which will be corrected.
No exceptions allowed for the due date.

Feedback on previous exams indicates that many students did very well, with a majority scoring between 90 to 100.
Students who find the first part of the course easy may struggle with the upcoming topics such as hypothesis testing.
If students keep up with the material, success in the course is achievable.
Encouraged students to seek help if they found aspects of the exam difficult, noting that asking questions prior to submission is an option.

Importance of following the course guidelines as laid out by the instructor for optimal performance in the class is emphasized.
- Students who ignore suggestions may still pass but will find it more difficult to achieve high grades.

Today's class will involve a review of confidence intervals to reinforce understanding.
- The topic will use the Flint water crisis as a case study to illustrate the importance of this statistical concept.
Context of the Flint Water Crisis
- The crisis involved the lead contamination of water due to the city’s decision to switch supply sources.
- Significant media coverage emphasized the health dangers associated with lead exposure, particularly in children.
- Discussion of systemic failures and public response to the crisis.
Students were asked to recognize the importance of clean, safe drinking water and the implications of water quality assessments on public health.

The assignment requires students to use an application to randomly select houses and determine contamination based on the Flint context.
- Students must continue sampling until they acquire at least 10 positive (yes) and 10 negative (no) responses regarding contamination.
- Understanding the proportion of contaminated houses is the goal.
Students will generate a confidence interval based on this data using a bootstrap distribution.
- About 1000 bootstrap samples are recommended for robustness.

Students will work in pairs on the written assignment.
The instructor encourages discussion amongst students about their assignment and the class material, maintaining an interactive atmosphere.
- Open invitation for students to ask questions along the way, ensuring clarity and comprehension.

Comments shared about the challenges of understanding various concepts in other courses (i.e. organic chemistry and chemistry).
Importance of peer study sessions noted, along with balancing course loads in future semesters.

Students should bring completed assignments to the following class session for feedback.
The instructor will utilize the end of class on Thursday for question clarification on the hypothesis testing topic, which will be introduced that day.
Students are reminded of office hours in case they need extra assistance navigating future assignments.
Discussion of financial implications of study abroad programs highlighted as an additional topic of concern among students.
