Explain what herd immunity is (hint: use Google to find the answer). Type your answer here: b. How many vaccinated people is 28% of the US population? Type your work and answer here: c. If 85% of the US population is needed for herd immunity, how many people would that be? Type your work and answer here: d. Write a linear equation for American vaccinations starting March 28th. Hint: let x = days since March 28th. So, for March 28, x = 0.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
According to the New York Times (March 27, 2021), 28% of the USA population will be vaccinated by March 28, with an average of 1.75 million new people vaccinated each day.
Public health experts say the United States will achieve herd immunity when between 70% and 90% of the US population is vaccinated.
