You wish to test the following at a significance level of =0.05=0.05. H0:p=0.33H0:p=0.33 H1:p>0.33H1:p>0.33 You obtain a sample of size n=699n=699 in which there are 246 successful observations. For this test, we use the normal distribution as an approximation for the binomial distribution. 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...
- (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 ....
- As such, the final conclusion is that...
- The sample data suggest that the population proportion is significantly greater than 0.33 at the significant level of = 0.05.
- The sample data suggest that the population proportion is not significantly greater than 0.33 at the significant level of = 0.05
- accept the null hypothesis
- reject the null hypothesis
- fail to reject the null hypothesis
- greater than
- less than (or equal to)
