You wish to test the following claim a significance level of $\displaystyle \alpha={0.001}$.

$\displaystyle {H}_{{o}}:{p}={0.63}$
$\displaystyle {H}_{{a}}:{p}<{0.63}$

You obtain a sample of size $\displaystyle {n}={379}$ in which there are 223 successful observations.

1. What is the test statistic for this sample?
    
   test statistic = Round to 3 decimal places.
   
   
2. What is the p-value for this sample?
   
   P-value = Use Technology Round to 4 decimal places.
   
   
3. The p-value is...
   • less than (or equal to) $\displaystyle \alpha$
   • greater than $\displaystyle \alpha$
   
   
   
4. This test statistic leads to a decision to...
   • reject the null
   • accept the null
   • fail to reject the null
   
   
   
5. As such, the final conclusion is that...
   
   • There is sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.63.
   • There is not sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.63.
   • The sample data support the claim that the population proportion is less than 0.63.
   • There is not sufficient sample evidence to support the claim that the population proportion is less than 0.63.
