The work has not been graded but I like the output that was submitted to me. Is it possible for the same prof to do the next assignment I will be submitting? If possible, I will greatly appreciate it.
7.) An instructor for a SAT prep course claims that the course will improve the test scores of students. The table shows the critical reading scores for 10 students the first two times they took the SAT. However before taking the test the second time, the students took a course to improve their critical reading scores. With α = 0.05, is there enough evidence to support the instructor’s claim? Does your answer change if α = 0.01? Why or why not?
Student 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Score (1st) 300, 450, 350, 430, 300, 470, 420, 370, 320, 410
Score (2nd) 400, 520, 400, 490, 340, 580, 450, 400, 390, 450
Identify the null hypothesis:
Identify the Alternate Hypothesis:
Reject or Do not reject the claim?
What if a=0.01 does this change your decision? Why or why not?
