Concept explainers

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.

Question

In Spring 2021, UMD decided to allow in-person graduation celebrations, despite COVID-19. You want to
throw a modestly-sized, indoor graduation party this week with some of your friends in your fraternity.
However, out of the 20 other people in your fraternity, 7 have tested positive for COVID-19, and you do not
know who those people are.
A) You plan to only invite 10 people, and you select them at random. What is the probability that exactly 3 of
the 10 people you invite are COVID-19 positive?
Pval
number (rtol=0.01, atol=D0.0001)
B) You plan to only invite 5 people, and you select them at random. What is the probability that 4 or more of
the 5 people you invite are COVID-19 positive?
Pval
number (rtol=0.01, atol=D0.0001)
C) You plan to only invite 10 people, and you select them at random. What is a 90% Confidence Interval on the
number of people you expect to be positive out of the 10 that you invite? Answer using an integer. To simplify
this part of the problem, you may assume that the overall positivity rate is fixed at 0.25.
Note: For the two integer fields for the lower and upper Cl on the number of positive cases, your integer
bounds should be conservative. That is, if the answer for lower bound is 2.3 people, then the lower bound
should be 2, and if the upper bound is 5.7 then then upper bound should be 6, etc.
integer
Tub

D) What is the maximum number of people you can invite to the party while still satifying the requirement that
there is no more than a 60% chance that one or more invited people is COVID-19 positive? To simplify this
problem, you may assume that the overall positivity rate is fixed at 0.25.
