Task #3 (Spole) Hypothesis Testing using Paired t-test Fifteen sets of identical twins were enrolled in a study to measure the effect of home environment on certain social attitudes. One twin in each set was randomly assigned to a minority environment or a home environment. The twin assigned to the minority environment went to live with a family in a minority community for a period of 1 year. At the end of the year, an attitudinal survey was administered. The data along with some descriptive statistics follow. Let alpha= 0.025 and test the hypothesis that living in the minority environment leads to higher scores on the attitudinal survey.
