Answer:
C. 2
Step-by-step explanation:
Cohen's d is a parameter used to express the standardised difference between two means. It is defined as the difference between the means divided by the pooled standard deviation.
In this case, the difference between both means (M2-M1) is 8. As for the pooled standard deviation, simply take the square root of the given pooled variance:

Therefore, the value of Cohen's d (d) is:

The answer is 44 because the equation is 352 divided 8. And 8 goes into 352 44 times. If you want to check the work you can also multiply 44 and 8, and it should be 352.
So the answer is 44
