2. A clinical psychologist is studying the differences in the number of Facebook® friends between identical twins raised apart. She believes that twins raised in different environments will have differences in the number of friends, which would help point to the influence of environmental factors over inherited factors on social outcomes. She divides the twins into two groups (“Twin 1” and “Twin 2”), collects the data and creates the table below. Using this table, enter the data into a new SPSS data file and run a paired-samples t test to test the claim that the identical twins raised apart will have a significantly different number of Facebook® friends.
