Question
You wish to test the following at a significance level of α=0.05α=0.05.
H0:p=0.41H0:p=0.41
H1:p>0.41H1:p>0.41
You obtain a sample of size n=567n=567 in which there are 257 successful observations.
For this test, we use the
For this sample...
- The test statistic (zz) for the data = (Please show your answer to three decimal places.)
- The p-value for the sample = (Please show your answer to four decimal places.)
- The p-value is...
- greater than αα
- less than (or equal to) αα
- (Recall that when p(-value) is low, the null must go; when p(-value) is high, the null must fly)
Base on this, we should ....- accept the null hypothesis
- reject the null hypothesis
- fail to reject the null hypothesis
- As such, the final conclusion is that...
- The sample data suggest that the population proportion is significantly greater than 0.41 at the significant level of αα = 0.05.
- The sample data suggest that the population proportion is not significantly greater than 0.41 at the significant level of αα = 0.05
