Answer:
19/25
Step-by-step explanation:
Convert the two fractions into decimals by dividing the numerator by the denominator. 19/25 = 0.76 and 5/20 = 0.25
Now you have: 0.76, 0,680, 0.33 and 0.25.
0.76 is the greatest rational number because it is closest to 1.0, making 19/25 the correct answer.
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
