Question

creating a two - way table from a scenario
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.
465 771 1,236 485 600
1,085 950 1,371 2,321

Explanation:

Step1: Calculate the number of vaccinated people

Total people \(n = 2321\), not - vaccinated \(=1085\), so vaccinated \(=2321 - 1085=1236\)

Step2: Calculate the number of vaccinated - negative

Vaccinated total \(=1236\), vaccinated - positive \(=465\), so vaccinated - negative \(=1236 - 465 = 771\)

Step3: Calculate the number of not - vaccinated - negative

Negative total \(=1371\), vaccinated - negative \(=771\), so not - vaccinated - negative \(=1371 - 771=600\)

Step4: Calculate the number of not - vaccinated - positive

Not - vaccinated total \(=1085\), not - vaccinated - negative \(=600\), so not - vaccinated - positive \(=1085 - 600 = 485\)

Step5: Calculate the positive total

Vaccinated - positive \(=465\), not - vaccinated - positive \(=485\), so positive total \(=465 + 485=950\)

Answer:

	Positive	Negative	Total
Not Vaccinated	\(485\)	\(600\)	\(1085\)
Total	\(950\)	\(1371\)	\(2321\)
