1. Pi1= Proportion of satisfied Verizon customers

    Pi2= Proportion of all other companies' satisfied customers.

2. Ho= Pi1 > Pi2

3. Ha= Pi1 </= Pi2

4. Alpha= .05

5. AND  :

6. Assumptions: These are both independently and randomly chosen, and our sample size is large enough to complete the test statistic.

7.

8. P-Value = .000

9. Since P-Value is less than alpha we reject our Ho at the .05 level of significance. There was sufficient evidence to say that Verizon has a superior satisfaction rate to all other companies combined.
