Two classes ofapproximately equal intelligence were selected. From one class, the teacher randomlyselected a group of students as experimental group for webcasting methods. Fromanother class, the teacher then selected another group of students as sample for existingstandard method of teaching. After one trimester, the same tests were given to thestudents. Their mean scores are shown in the following table:Method of teachingMean scoreStandard deviation Sample sizeWebcasting methodX, = 82.3S = 12dt daiw bo%3Dn = 42otExisting standardmethodX, = 78.5S2 = 9%3D2N; = 38Test the hypothesis whether or not the webcasting method of teaching social sciencessubjects is more effective than the existing standard method of teaching.
