Two independent samples of respective sizes 7 and 10, respective means 102 and 130, and respective standard deviations 9 and 8, were selected from two normal populations with equal variances. Need to test the null hypothesis that the two population means are equal versus they are different. Based on these two samples, we can conclude the following about this test at a = 0.05 0.01 O a. the value of the test statistic is 3.32768 and the the cut-off value is 2.977 , so we reject HO b. the value of the test statistic is 3.09914 and the the cut-off value is 1.28 , so we reject HO c. None of these O d. the value of the test statistic is 3.09914 and the the cut-off value is 1.64, so we accept HO O e. the value of the test statistic is 3.32768 and the the cut-off value is 2.602, so we accept H0
