Suppose that you were trying to determine if the population


Suppose that you were trying to determine if the population proportion of Americans that currently believe that nuclear power is extremely/very dangerous to the environment was less than 50%. You decide to test the null hypothesis Ho: p = 0.50 versus Ha: p < 0.50.In 1993, the General Social Survey included a question that asked its participants if they felt that nuclear power plants were extremely/very dangerous to the environment. Out of the 1419 surveyed, 630 said yes. What is the value of the test statistic for this problem?

 

-4.22

 

4.22

 

-16.42

 

-16.83

 

16.83

 

16.42

 

2. For a test of Ho: p = 0.5, the z test statistic equals 1.74. Find the p-value for Ha: p > 0.5.
