SAT coaching: A sample of 10 students took a class designed to improve their SAT math scores. Following are their scores before and after the class. Can you conclude that the mean increase in scores is greater than 15 points? Let μ₁ represent the mean score after the class and μμ₁₂. Use the a=0.10 level and the P-value method with the TI-84 Plus calculator.

Question
SAT coaching: A sample of 10 students took a class designed to improve their SAT math scores. Following are their scores before and after the class. Can you conclude that the mean increase in scores is greater than 15 points? Let μ₁ represent the mean score after the class and μμ₁ −μ₂. Use the a=0.10 level and the P-value method with the TI-84 Plus calculator. Before After Send data to Excel Part 1 of 4 = 383 334 420 H₁: >15 Ma (a) State the appropriate null and alternate hypotheses.
