Question

Personality psychologists hypothesize that more anxiety is related to more negative externalizing behaviors (e.g., causing fights). The table below contains the response from a sample of middle school students. What can the psychologist conclude with an α of 0.01?

anxiety	neg. behavior
17 22 29 34 15 20 27 20 31 24 26 21	9 7 11 3 11 6 2 7 6 9 5 10

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:  ---Select--- 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 and/or select "na" below.
effect size =  ;    ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

There is a significant positive relationship between anxiety and negative externalizing behaviors.There is a significant negative relationship between anxiety and negative externalizing behaviors.    There is no significant relationship between anxiety and negative externalizing behaviors.
