- For this study, we should use ---- ?
2. Your friend Vivian helped you with the null and alternative hypotheses...
H0: μ1=μ2=μ3H0: μ1=μ2=μ3
H1:H1: At least one of the mean is different from the others.
3. The test-statistic for this data = ? (Please show your answer to 3 decimal places.)
4. The p-value for this sample = ? (Please show your answer to 4 decimal places.)
5. The p-value is ? αα
-less than (or equal to) alpha
-greater than alpha
6. Base on this, we should ? hypothesis
-accept the null hypothesis
-accept the alternative hypothesis
-reject the null hypothesis
-fail to reject the null hypothesis
7. As such, the final conclusion is that...
- Base on the sample data, there is not sufficient evidence to conclude the claim that the starting salaries for new college graduate are different depending on the positions at αα = 0.05.
