fill in the blanks

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 = 0.05 given the following data Group 1: Internship 12.25 8.75 12.5 11 12 14.25 11.25 12 12.5 11.5 9.25 Group 2: Co-op Group 3: Work Study 11.25 3. The test-statistic for this data 14 14.75 12.75 13.25 11.75 13.75 12.5 13.75 14.5 12.25 1. Your friend London helped you with the null and alternative hypotheses... Ho H₁ H₂ H3 H₁: At least two of the means differ from each other. 2. For this study, we should use ANOVA = 11.5 13 13.75 10 14.25 13.75 13 13 14.25 14.25 13.5 (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 less than (or equal to) alpha ✓ ✓ a 6. Base on this, we should reject the null hypothesis hypothesis 7. As such, the final conclusion is that... There is insufficient evidence to support the claim that position is a factor in starting salaries for new college graduates. There is sufficient evidence to support the claim that position is a factor in starting salaries for new college graduates.
