Answer:
Step-by-step explanation:
27x + 12y = -216
8x - 12y = -64
35x = -280
x= -8
2(-8) - 3y = -16
-16 - 3y = -16
-3y = 0
y = 0
(-8, 0)
Answer:
-0.67
Step-by-step explanation:
Given that :
Population mean, μ = 4.7
Sample size, n = 68
Sample mean, M = 4.3
Sample standard deviation, s = 0.6
The effect size, d can be obtained using the relation :
d = (M - μ) / s
d = (4.3 - 4.7) / 0.6
d = - 0.4 / 0.6
d = - 0.66666
d = - 0.67
Hence, effect size associated with a single-sample t test is - 0.67
