A health psychologist tests a new intervention to determine if it can change healthy behaviors among siblings. To conduct the this test using a matched-pairs design, the researcher gives one sibling an intervention, and the other sibling is given a control task without the intervention. The number of healthy behaviors observed in the siblings during a 5-minute observation were then recorded.

(a) Test whether or not the number of healthy behaviors differ
at a 0.05 level of significance. State the value of the test
statistic. (Round your answer to three decimal places.)
(b) Compute effect size using eta-squared. (Round your answer to
two decimal places.)
