Explanation / Answer

H0: P = 0.12

H1: P < 0.12

The test statistic z = (p - P)/sqrt(P * (1 - P)/n)

                             = (0.106 - 0.12)/sqrt(0.12 * 0.88/1585)

                             = -1.72

The critical value is z0.05 = -1.645

As the test statistic value is less than the critical value -1.72 < -1.645), so the null hypothesis is rejected.

so Option - A is the correct answer.
