Research psychologists at the University of Minnesota are interested in comparing the average critical reading SAT scores for 9 sets of identical twins, one of whom was raised in a family with no other children (no siblings) and one of whom was raised in a family with other children (with siblings). The reading SAT score for each twin was recorded and then entered into Excel. Based on this paragraph of text, use the correct excel output above to answer the following question. What is the 90% confidence interval for uwith Siblings HNo Siblings? O a. (-10.5812, 122.5812) O b.(-114.4492, 2.4492) O C. (-122.5812, 10.5812) O d. (-2.4492, 114.4492) O e.
