1) a) Option-D) Fail to reject H0 . Because p-value , 0.0749 is greater than alpha = 0.01
b) Option-D) Fail to reject H0 . Because p-value , 0.0749 is greater than alpha = 0.05
c) Option-A) Reject H0 . Because p-value , 0.0749 is less than alpha = 0.1
2) p-value = P(Z < -2.05) = 0.0202
Option-A) 0.0202. Reject null hypothesis
3) test statistic = (890 - 870) / (127/sqrt(63)) = 1.25
critical value = Z0.05 = 1.645
Rejection region, z > 1.645
Option-D) Fail to reject H0 because the standardized test statistic is not in the rejection region

Identify the null hypothesis, alternative hypothesis, test statistic, P-value, conclusion about the null hypothesis, and final conclusion that addresses the original claim. A test of sobriety involves measuring the subject's motor skills. A study of n = 20 randomly selected sober subjects take the test and produce a mean score of X = 41.0, and we know that o = 3.7. At the 0.01 level of significance, test the claim that the true mean score for all sober subjects is...
