1. The South Beach Diet is advertised to be very effective in helping people lose weight. A random sample of 10 women were in a study to see if this is true. They participated in this diet for 10 weeks. Their "Before" and "After" weights are listed below: Note: The researcher assumes that the data is normally distributed.

We are interested in determining whether participating in the diet decreases the women's weights, as measured by this study. Should we do a paired design (matched pairs) test OR a test of two samples? Clearly choose the design and explain your choice.
