' --- - vI Taylor Swift has recently received poor reviews after her concerts in the Southeastern United States, a region where country music is very popular. She hires a social psychologist to figure out why. The social psychologist believes her lower reviews could be blamed on her genre switch from country music to pop. The social psychologist asks Taylor what her reviews were from 2006-2011, and she says they were a 9.34 (on a scale from 1-10) with a standard deviation of 2.11. To examine if her recent reviews are lower than her early career wages, the psychologist takes a sample of 49 of Taylor's recent concert reviews. He finds that her average review in the Southeastern United States was 8.76. He conducted a statistical test to examine this hypothesis. Can you replicate this test? 27.
