a grade never repeated repeated n, = 1 349 x, = .30 n2 = 86 X2 = -.04 S2= 1.17 Si=.97 (a) The researcher is wondering that the average height of children who never re- peated a grade is higher than the average of children who repeated. Set up the appropriate H. and H,. (b) Propose a formula to calculate the test statistic and report the result. (Assumetwo populations have equal variance and both populations follow normal distributions). (c) Find the P-value and make your conclusion on a = .05.
