In a random sample of 275 people that were tested for the Norcovirus, it was found that 215 did not have the virus. A 95% confidence interval was constructed to estimate the proportion of the population that does not have the Norcovirus. This confidence interval came out to be (0.73, 0.83). Select the correct intrepretation of this interval. O We are 95% confident that the proportion of people in the sample that tested postitive for the Norcovirus is between 73% and 83%. O We are 95% confident that the proportion of people in the sample that tested negative for the Norcovirus is between 73% and 83%.

Concept explainers

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

100%

In a random sample of 275 people that were tested for the Norcovirus, it was found that 215 did not have
the virus. A 95% confidence interval was constructed to estimate the proportion of the population that does
not have the Norcovirus. This confidence interval came out to be (0.73, 0.83).
Select the correct intrepretation of this interval.
O We are 95% confident that the proportion of people in the sample that tested postitive for the
Norcovirus is between 73% and 83%.
O We are 95% confident that the proportion of people in the sample that tested negative for the
Norcovirus is between 73% and 83%.
O We are 95% confident that the proportion of the population that have the Norcovirus is between 73%
and 83%.
O We are 95% confident that the proportion of the population that does not have the Norcovirus is
