Question

A physician hypothesizes that more labor pain is related to more infant bonding. The table below contains data for mothers' labor pain (higher score indicates more pain) and the amount of hours spent bonding with their infant after birth. What can the physician conclude with an α of 0.01?

labor pain	infant bonding
8 7 2 4 3 6 5 3 3 5 7	8 5 2 4 5 7 2 1 4 4 6

a) What is the appropriate statistic?
---Select--- na Correlation Slope Chi-Square  
Compute the statistic selected above:   

b) Compute the appropriate test statistic(s) to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
p-value =   ; Decision: Reject H0 Fail to reject H0  

c) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input "na".
effect size =    na trivial effect small effect medium effect large effect
