C. a large variance for the difference scores and a small standard error
D. a large variance for the difference scores and a large standard error
Answer:
A) a small variance for the difference scores and a small standard error
Step-by-step explanation:
Since the difference scores are obtained by subtracting one variable form another, if the difference scores are consistent between treatments, then the variance will be small. The higher the variance, the higher the standard error. So if the variance is small, then the standard error will also be small.
Answer:
Step-by-step explanation:
let us assume that the amount in her accounts compounds annually
Given data
principal p= $160
interest rate r= 3%= 0.03
time t= 30 years
At the end of 30 years the money she will will have can be expressed as
A= P(1+r)^t
A= 160(1+0.03)^30
A= 160(1.03)^30
A= 160*2.42726
A= $388.36
in 30 years she will have $388.36
Answer:
20 m/s
Step-by-step explanation:
Distance = rate * time
400 m = rate * 20 seconds
Divide each side by 20 seconds
400m/ 20 seconds = rate
20 m/second = rate
