Answer:
a. 0.047
b. Unlikely.
Step-by-step explanation:
a. The probability of a test result being wrong for a person not using mrijuana = 8 / 170 = 0.047.
b. As the probability for a wrong result is < 0.05 we can say that the test is unlikely to be wrong.

Proportion set up....
small 4 ? small
----- --------
big 5 135 big
Cross multiply 4x135= 540
and then divide 540/5= 108
