We want to compare the performances of two customer service centers in terms of average call response time and find out if the difference is statistically significant or if the difference is a chance occurrence. Call response time is the amount of time it takes from when the caller dials into the customer service center, to the time they are connected with the appropriate representative. We randomly select 50 calls from each customer service center, and the call response time is recorded and classified into 2 groups based on the customer service center.

Can this case be tested using a two-sample t-test? Why?
