July 9, 2019There were two independent groups who took a school course by different modes. The first sample of students took the course in the online and the second sample took the course in the conventional face to face mode. Using the sample data, determine if there is significant difference in the scores between the two groups.
Ho: (u1-u2=0) no difference
H1: (u1-u2) <> there is a difference
?= 0.05 t critical= +_ 2.01 n
n1= 10, n2=10
m1=93, m2=85
s1=20,s2=20
We only need to calculate the test statistic to complete the test.
