Spring Break vs. COVID19: The Real Impact of Ignoring Social Distancing

US COVID-19 data, CA COVID-19 data, Santa Clara County COVID-19 data.

Contamination Animation

Los Alamos National Laboratory paper (non peer-reviewed) creates much higher confidence interval for the R0 of 2019-nCoV:

"the R0 value is likely to be between 4.7 and 6.6"

"Our estimate of the time from initial exposure to symptom onset is 4.2 days with a 95% confidence interval (CI for short below) between 3.5 and 5.1 days"

**3 Week Remote Learning 3/30-4/3 **** Days 39 & 40**) Finish chi-square. Review correlation and regression to prepare for Chapter 27. Watch the **Week 3 video lesson**.

Fill in the first two columns of the inference guide while watching the video.

After watching the Week 3 video, complete assignments 39A and 40A below.

**39A:**

1) Complete the Investigative Task. Do a complete chi-square test
for
each
question
1,2,3.

**40A:**

1) Complete the Correlation and Regression Review (TI
Calculator Tips Here)

2) Study / re-learn about regression and the associated calculator procedures.

**2 Week Remote Learning 3/23-27 B_Day 37 & Day 38)**

Complete the class notes by watching the video.

Practice chi-square calculator
shortcuts. Learn the importance of and how to calculate standardized residuals
(see TI download options under the assignment).

Discover the chi-square test of independence.

Homogeneity - many groups asked 1 question (question = variable, answers = categories)

Independence - one group asked 2 questions.

Complete the chi-square inference guide.

**37A: KEY**

1) pg. 642-648 / 23, 24, (problem 23 think back to what we did at the beginning of the year. We tested for independence with segmented bar charts then with P(A) = P(A|B). Now the independece X2 test provides "wiggle room" to accomodate natural sampling variability.)

However, with a low X2 value (and high p-value) we don't declare independence we only declare their isn't evidence of an association. (Makes me think it should really be called chi-squared test for association).

**38A: KEY**

1) Complete side one of the Day 38 handout (Binging and Politics).
