Question

You wish to test the following claim a significance level of α=0.01.

Ho:p=0.19
Ha:p<0.19

You obtain a sample of size n=334 in which there are 49 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) αα
   • greater than αα
   
   
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 0.19.
   • There is not sufficient evidence to warrant rejection of the claim that the population proportion is less than 0.19.
   • The sample data support the claim that the population proportion is less than 0.19.
   • There is not sufficient sample evidence to support the claim that the population proportion is less than 0.19.
