Question: There are two major cell phone providers in the Colorado

There are two major cell phone providers in the Colorado Springs, Colorado, area, one called HTC and the other, Mountain Communications. We want to investigate whether there is a difference in the proportion of times a customer is able to successfully access the Internet. During a one-week period, 500 calls were placed at random times throughout the day and night to HTC; 450 of the calls were successful. A similar one-week study with Mountain Communications showed that 352 of 400 calls were successful. At the .01 significance level, is there a difference in the percent of time that cell phone connections are successful?
