Q1. You conducted a study (using a matched-pairs design) to measure the differences in body weight (lbs) between identical twins to see if they are significantly different. Each row displays twins (siblings are matched on the same row). You hypothesize that the older twin (older by a few seconds) will weigh less than the younger twin:

1. Using SPSS, examine whether there is a difference between the older (twin 1) and younger twins (twin 2) at a .05 level of significance. Copy and paste the table generated by SPSS to this Word doc (3 pts).
2. State the value of the test statistic and the decision to retain or reject the null hypothesis (1 pt).
3. Compute effect size using omega-squared (1 pt).
4. Did the results support your hypothesis? Explain (1 pt).
