**Question description**

You are being asked to compare Adult Attachment Style (EV-Dismissive and Preoccupied) with Self-Esteem (RV). Questions 1 - 5

- State the null and alternative hypotheses.
- Ho: µ
_{1}= µ_{2}, Ha: µ_{1}≠ µ_{2} - Ho: µ
_{1}- µ_{2 }= 0, Ha: µ_{1}- µ_{2 }≠ 0 - Ho: µ
_{1}- µ_{2 }≠ 0, Ha: µ_{1}- µ_{2 }= 0 - Ho: µ
_{1}≠ µ_{2}, Ha: µ_{1}= µ_{2} - Both ‘a’ and ‘b’

- Ho: µ
- Were any of the assumptions and conditions violated?
- Yes, the assumption of normality
- Yes, the assumption of equal variances
- Both ‘a’ and ‘b’
- No, assumptions were met
- Not enough information

- What is the appropriate t-statistic and p-value?
- t(77) = 1.98, p = .052
- t(137) = 1.99, p = .049
- t(77) = 1.99, p = .049
- t(137) = 1.98, p = .052
- Both ‘a’ and ‘b’

- What is your decision?
- Reject Ho, Dismissive scored higher than Preoccupied
- Reject Ho, Preoccupied scored higher than Dismissive
- Fail to reject Ho, Dismissive scored higher than Preoccupied
- Fail to reject Ho, Preoccupied scored higher than Dismissive
- None of the above

- Is Cohen’s d appropriate? If so compute it?
- It isn’t appropriate
- No, d = .37, small to medium effect
- Yes, d = .37, large effect
- Yes, d = .37, small to medium effect
- Yes, d = -.37, large effect

- State the null and alternative hypotheses.
- Ho: µ
_{1}= µ_{2}, Ha: µ_{1}≠ µ_{2} - Ho: µ
_{1}- µ_{2 }= 0, Ha: µ_{1}- µ_{2 }≠ 0 - Ho: µ
_{1}- µ_{2 }≠ 0, Ha: µ_{1}- µ_{2 }= 0 - Ho: µ
_{1}≠ µ_{2}, Ha: µ_{1}= µ_{2} - Both ‘a’ and ‘b’

- Ho: µ
- Were any of the assumptions and conditions violated?

- t(185) = 2.72, p = .007
- t(201) = 2.74, p = .007
- Both ‘a’ and ‘b’

- What is your decision?
- Reject Ho, Fearful scored higher than Dismissive
- Reject Ho, Dismissive scored higher than Fearful
- Fail to reject Ho, Dismissive scored higher than Fearful
- Fail to reject Ho, Fearful scored higher than Dismissive

- No, d = .39, medium effect
- Yes, d = .39, large effect
- Yes, d = .39, small to medium effect
- Yes, d = -.37, small effect

- State the null and alternative hypotheses.
- Ho: µ
_{1}≠ µ_{2}, Ha: µ_{1}= µ_{2} - Ho: µ
_{1}= µ_{2}, Ha: µ_{1}≠ µ_{2} - Ho: µ
_{1}- µ_{2 }= 0, Ha: µ_{1}- µ_{2 }≠ 0 - Ho: µ
_{1}- µ_{2 }≠ 0, Ha: µ_{1}- µ_{2 }= 0 - Both ‘b’ and ‘c’

- Ho: µ
- Were any of the assumptions and conditions violated?
