Answer: 3.21
Step-by-step explanation:
As per given description, we have
Population proportion : 
Sample size : n= 300
Sample proportion : 
Test statistic for population proportion :-
![z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}\\\\\\=\dfrac{0.71-0.62}{\sqrt{\dfrac{0.62(1-0.62)}{300}}}\\\\=3.21155595947\ \ \\\\\approx3.21 \ \ \text{[Rounded to 2 decimal places. ]}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B%5Chat%7Bp%7D-p%7D%7B%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B0.71-0.62%7D%7B%5Csqrt%7B%5Cdfrac%7B0.62%281-0.62%29%7D%7B300%7D%7D%7D%5C%5C%5C%5C%3D3.21155595947%5C%20%5C%20%5C%5C%5C%5C%5Capprox3.21%20%5C%20%5C%20%5Ctext%7B%5BRounded%20to%202%20decimal%20places.%20%5D%7D)
Hence, the test statistic for this hypothesis test for a proportion= 3.21
I think it’s c but don’t go with me see if others answer with a different answer :)
