Question
The following three independent random samples are obtained from three normally distributed populations with equal variances. The dependent variable is starting hourly wage, and the groups are the types of position (internship, co-op, work study). We are testing the claim that position is a factor in starting salaries for new college graduates. at a = 0.2 given the following data Group 1: Internship 11.75 12.5 10.75 11.5 11.75 11.75 12 11.5 11.5 8.5 Group 2: Co-op 13.75 12 11.5 12.75 12 13.5 13.5 11.5 12 13 1. Your friend Christopher helped you with the null and alternative hypotheses... Ho: μι = μ2 = 13 H₁: At least two of the means differ from each other. 2. For this study, we should use Select an answer ✓ 3. The test-statistic for this data = Group 3: Work Study 11 11.5 10.75 14.25 13 13.75 14.75 11.75 14.5 12.5 (Please show your answer to 3 decimal places.) (Please show your answer to 4 decimal places.) 4. The p-value for this sample= 5. The p-value is Select an answer 6. Base on this, we should Select an answer 7. As such, the final conclusion is that... α hypothesis There is sufficient evidence to support the claim that position is a factor in starting salaries for new college graduates. O There is insufficient evidence to support the claim that position is a factor in starting salaries for new college graduates.
