Question 91555
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.
----------------------- 
What is your decision regarding the null hypothesis? 
Note: It is recommended that you use the five-step hypothesis-testing procedure in solving the following problems.
