Answer:
-2, -1, 0, 1
Step-by-step explanation:
Let the 4 numbers be x,x+1, x+2, x+3
Then we have the equation:-
5(x+3)-2(x+1) = 7
5x - 2x + 15 - 2 = 7
3x = - 6
x = -2
so the integers are -2, -1, 0, 1

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 =
