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:
351.658 square in
Step-by-step explanation:
First find the circumference of the circle
C = 25.13
Find area of the circle
A = 50.27
Multiply the circumference by the height
25.13 × 10 = 251.3
Add 251.3 with 50.27 twice
251.13 + 50.27 + 50.27 ≈ 351.658
Therefore your answer is D) 351.658 square in
