Question 168777
I used-a 2-proportion z-test on my TI calculator to get the following results:
Ho: p1 = p2
Ha: p1 is not equal to p2
-----------------------------
Test statistic: z(-.74-0.84) =  -3.881922
p-value: 0.00010367
-------------------
Conclusion: Since the p-value is less than 5%, reject Ho.
p1 is not equal to p2
==============================
