**Problem 7: Testing Equality of Population Proportions**

A sample of size 100 selected from one population has 60 successes, and a sample of size 150 selected from a second population has 95 successes. The test statistic for testing the equality of the population proportions is equal to:

a. -0.5319  
b. 0.7293  
c. -0.419  
d. 0.2702  

**Explanation**: 

This problem involves comparing the proportions of successes in two independent samples to test if the proportions are statistically significantly different. You are given the sample sizes and number of successes for each sample and need to determine the appropriate test statistic from the given options to assess the equality of the population proportions.
