A school conducts an interest aptitude test for final students, the teacher think that the average student aptitude test score is 470 with a known standard deviation value of 10, so the school takes a sample of the talent interest test value data from 9 students as follows: Student A Score 440 Student B Score 460 Student C Score 485 Student D Score 509 Student E Score 496 Student F Score 477 Student G Score 457 Student H Score 465 Student I Score 495 The hypothesis put forward by the management department is as follows: HO: μ = 470 H1: μ # 470 By using a = 5%, testing in two tails (two sides), test this opinion and give the conclusion! Note: Do this problem using manual formulas in a structured manner, don't use calculations from excel, minitab, or the like.
