Alex wants to test the reliability of “lie detector tests,” or polygraph tests. He performs a polygraph test on a random sample
VladimirAG [237]

The correct statement is test is reliable and authentic as the probability of no false positives is more than 0.5

Given that

H_o:P= 0.50\\\\H_1:P>0.50

Now following calculations to be done to reach out the conclusion

There is no false positive as

= 100 - 5.5

= 94.5%

\hat P =0.945, n = 12

Now

z = \frac{\hat P - P}{\sqrt\frac{P(1-P)}{n} }\\\\=\frac{0.945-0.5}{\sqrt\frac{0.5\times0.5}{12} }  \\\\= 3.08

So

P value = P(z >3.08) = 0.0010

Therefore we can conclude that test is reliable and authentic as the probability of no false positives is more than 0.5
