Use a comma to separate answers as​ needed.) b. Choose the correct conclusion below. A. Reject Upper H 0. There is sufficient evidence to warrant rejection of the claim that pequals1 divided by 6. B. Reject Upper H 0. There is not sufficient evidence to warrant rejection of the claim that pequals1 divided by 6. C. Fail to reject Upper H 0. There is sufficient evidence to warrant rejection of the claim that pequals1 divided by 6. D. Fail to reject Upper H 0. There is not sufficient evidence to warrant rejection of the claim that pequals1 divided by 6.

Answer 1

Given that

Test statistic z = -2,

Hypothesis:

Note that alternative hypothesis is not given, I assume it is one tailed , because upper H0 IS mentioned.

Critical value at 1% level of significance is 2.33

Since calculated |z| = |-2| = 2 is less than critical value do not reject null hypothesis.

Fail to reject Upper H 0. There is not sufficient evidence to warrant rejection of the claim that p equals1 divided by 6.
