Answer:
The answer is
2.451
Step-by-step explanation:
52% oppose making all US colleges free
Total population n = 600
X = 342 people who supports taxpayer funded free college
P = 0.52
N = 600
P^ = x/n
= 342/600
= 0.57
Test statistic
Z = ^p-p/√p(1-p)/n
Z= 0.57-0.52/√0.52(1-0.52)/600
Z = 0.05/√0.000416
Z = 0.05/0.020496
Z = 2.451 or 2.45
That is the value of the test statistic.
