: The following hypotheses are given.
H0pie=0
H1pie does not =1

A sample of 120 observations revealed that p = .30. At the .05 significance level, can the null hypothesis be rejected?
State the decision rule.
Compute the value of the test statistic.
What is your decision regarding the null hypothesis?

You can put this solution on YOUR website!
The following hypotheses are given.
Ho: p=0
H1: p does not =1
Comment: Your Ho and H1 are meaningless.
------------------------
A sample of 120 observations revealed that p = .30. At the .05 significance level, can the null hypothesis be rejected?
State the decision rule. If by this you mean the critical values the
answer is z = + or - 1.96
-------------------------------
Compute the value of the test statistic.
z(0.3) = (0.3 - p)/sqrt(pq/120)
Comment: We would need a realistic "p" from Ho.
