The value of the test statistic is 2.59.

<h3>What is Test Statistics?</h3>

A number derived from a statistical test of a hypothesis is the test statistic. It displays how closely your actual data fit the distribution predicted by the statistical test's null hypothesis.

Here, the percentage of residents favored construction is 34%.

p\leq 0.31\\p > 0.31

The test statistics is given by,

Z=P-\frac{p}{\sqrt{p(1-p)n} }

Here n=1600, P=0.34 and p=0.31,

Putting the values,

Z=0.34-\frac{0.31}{\sqrt{0.31(1-0.31)1600} }\\=2.59

Test Statistics = 2.59

Therefore, the value of test statistics is 2.59.
