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.

**Traffic Fatalities and Blood Alcohol Concentration (BAC) Analysis**

According to a certain government agency for a large country, the proportion of fatal traffic accidents in which the driver had a positive blood alcohol concentration (BAC) is 0.33. Suppose a random sample of 107 traffic fatalities in a particular region results in 46 that involved a positive BAC.

**Research Question:**
Does the sample evidence suggest that the region has a higher proportion of traffic fatalities involving a positive BAC than the country at the α = 0.01 level of significance?

**Hypothesis Testing Requirements:**

- The expression $np_0(1 - p_0)$ should be evaluated and checked if it is greater than or equal to 10.
- Input values are required to complete: a selection for the expression value, the sample size, and the population size percentage.

- The sample must be less than 5% of the population size.
- The conditions for testing the hypothesis should be either confirmed as satisfied or not satisfied.

(Note: Ensure computations are rounded to one decimal place as needed.)
