In an attempt to compare the performance of students with more than one electronic gadget and those with only one or none, the mean grades of students and the standard deviations were taken and are shown in the table below. Mean Standard Sample deviation Students with 0 - 1 gadgets Students with more than 1 gadget X1 = 83 X2 = 79 Is there a significant difference between the mean grades of students with more than one S1 = 10 S2 = 14 N¡ = 12 n2 = 12 electronic gadget and those with one or none? Use a = 0.05 and use a two-tailed test.
