I think it is A because i think it is the only one that makes sense
Answer:
0.5
Step-by-step explanation:
Solution:-
- The sample mean before treatment, μ1 = 46
- The sample mean after treatment, μ2 = 48
- The sample standard deviation σ = √16 = 4
- For the independent samples T-test, Cohen's d is determined by calculating the mean difference between your two groups, and then dividing the result by the pooled standard deviation.
Cohen's d = 
- Where, the pooled standard deviation (sd_pooled) is calculated using the formula:

- Assuming that population standard deviation and sample standard deviation are same:
SD_1 = SD_2 = σ = 4
- Then,

- The cohen's d can now be evaliated:
Cohen's d = 
Answer:
this answer is B!!
Step-by-step explanation:
Answer:
make the denominators ( bottom number ) the same and whatever u do to that do to the top
Step-by-step explanation:
e.g ½ - ⅓
make the common denominator 6
to get from 2 to 6 u times by 3 so it wud be 3/6
and then to get from 3 to 6 u times by 2 so do the same to the numerator (top number) so u get 2/6
3/6 take away 2/6 is 1/6
:)
The least is 2/7 then 1/2 then 5/6 and the greatest is 4/2
