Answer:
-4.317
Step-by-step explanation:
The z test statistic for testing of 1-proportion can be computed as

We know that
phat=x/n.
We know that x=40 and n=120.
Thus,
phat=40/120=0.3333
p=hypothesized proportion=0.53
q=1-p=1-0.53=0.47
So, required z-statistic is


z=-4.317.
Thus, the required test statistic value for given hypothesis is z=-4.317.
