Sagot :
In the first randomization, the mean of A and B will be 12.5 and 11.46 respectively.
How to calculate the mean?
The mean for the first randomization will be:
Mean of A = (13.6 + 12.14 + 15.9 + 11.2 + 3.7) / 5
= 62.5/5
= 12.5
Mean of B = (5.2 + 8.2 + 11.5 + 13.8 + 14.6) / 5
= 57.3/5
= 11.46
For the second randomization, the mean will be:
A = (8.2 + 13.8 + 15.9 + 9.2 + 9.7)/5
= 56.8/5
= 11.36
B = (12.1 + 14.6 + 13.6 + 11.2 + 11.5)/5
= 63/5
= 12.6
For the third randomization, the mean will be:
A = (8.2 + 9.7 + 11.5 + 14.6 + 15.9)/5
= 59.9/5
= 11.98
B = (12.1 + 13.8 + 13.6 + 11.2 + 9.2)/5
= 59.9/5
= 11.98
