When the necessary conditions are met, a two-tailed test is being conducted to test the difference between two population proportions. The two sample proportions are and , and the standard error of the sampling distribution of is 0.0085. The calculated value of the test statistic will be z = 3.41.
Two-Tailed Test
A statistical test of hypothesis where the area of interest spans both tails of the distribution, allowing for investigation of deviations in two opposite directions.
Sample Proportions
The fraction or percentage of observations in a sample that fall into one particular category or class.
Standard Error
The standard deviation of the sampling distribution of a statistic, commonly the mean, indicating the variation of a sample statistic from the population parameter.
