Obviously the ans should be a
1011.59 rounded off to 1011.6 (OPTION THREE)
Answer:
The first one
Step-by-step explanation:
The absolute value of a negative number is the same number but positive if that makes sense. ( ex absolute value of -5 is 5 )
The absolute value of a positive number is literally that number ( ex. absolute value of 6 is 6 )
Thus, the absolute value of 1 is 1 and the absolute value of -99 is 99
99 is greater than 1 which means that the absolute value of -99 is greater than the absolute value of 1
Thus, the answer is the first one
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:
![S=\sqrt{S^2}\\S=\sqrt{16} \\S= 4](https://tex.z-dn.net/?f=S%3D%5Csqrt%7BS%5E2%7D%5C%5CS%3D%5Csqrt%7B16%7D%20%5C%5CS%3D%204)
Therefore, the value of Cohen's d (d) is:
![d=\frac{M_{2} -M_{1}}{S} \\d=\frac{8}{4}\\d=2](https://tex.z-dn.net/?f=d%3D%5Cfrac%7BM_%7B2%7D%20-M_%7B1%7D%7D%7BS%7D%20%5C%5Cd%3D%5Cfrac%7B8%7D%7B4%7D%5C%5Cd%3D2)
-0.35, -0.3, 0.5, 0.55
is your answer
hope this helps
