How do states stack up against each other in SAT scores? To compare State 1 and State 2 scores, random samples of 100 students from each state were selected and their SAT scores recorded with the following results. (Use ₁ for State 1 and ₂ for State 2.) Sample Size Standard Deviation 100 196 100 163 State State 1 State 2 Mean ܕ ܐ 1,124 1,049 (a) Use the critical value approach to test for a significant difference in the average SAT scores for these two states at the 5% level of significance. State the null and alternative hypotheses.
