The value of t obtained is 4.76
Given,
Mean of group 1, = 10
Mean of group 2, = 12
= 5
= 8
Number of individuals per group, n = 6
The degrees of freedom are calculated as:
= ( 8-1) + (8-1) = 7 + 7 = 14
The difference between sample means is:
=
= 10 - 12 = 2
Here n is equal for both groups which is = 8
Now,
The standard deviation of sample 1 :
The standard deviation of sample 2 :
Now, we have to calculate the standard error for the difference of the means.
MSE =
=
=
MSE = 0.7237
Then, the standard error can be calculated as:
Now we can calculate t :
