ACT Scores A survey of 1000 students nationwide showed a mean ACT score of 21.4. A survey of 500 Tennessee scores showed a mean of 21.3. If the population standard deviation in each case is 3, can we conclude the national average is greater than the Tennessee average? Use a=0.10 and use μ₁ for nationwide mean ACT score.
