Question

in a study, 1,085 out of 2,321 people did not receive a flu vaccination. 465 people were vaccinated and tested positive for the flu. a total of 1,371 participants tested negative. create a two - way table for this scenario.

Explanation:

Step1: Find number of vaccinated people

Total number of people is 2321, and 1085 did not receive vaccination. So number of vaccinated people is $2321 - 1085=1236$.

Step2: Find number of vaccinated and negative

We know 465 vaccinated people tested positive. Since there are 1236 vaccinated people in total, number of vaccinated and negative is $1236 - 465 = 771$.

Step3: Find number of not - vaccinated and positive

Total number of positive cases is $2321 - 1371=950$. Since 465 positive cases are vaccinated, number of not - vaccinated and positive is $950 - 465 = 485$.

Step4: Find number of not - vaccinated and negative

We know 1085 people are not vaccinated. So number of not - vaccinated and negative is $1085 - 485 = 600$.

Answer:

	Positive	Negative	Total
Not Vaccinated	485	600	1085
Total	950	1371	2321
