Answer:
rotation about a point
Step-by-step explanation:
You can use the process of elimination for the first three options, as you can see that this is not what is happening. The final option, rotation, fits.
Answer:
Standard error = 0.34
t-statistic = 11.18
Step-by-step explanation:
Given Data:
Mean difference d = 3.8
Standard deviation S.D = 1.36
Number of people = 16
The appropriate test are:
1. Standard error
2. T- statistic
1. Calculating the standard error using the formula;
Standard error = S.D/√n
= 1.36/√16
= 1.36/4
= 0.34
2. Calculating the t-statistic using the formula;
t-statistic = d/(S.D/√n)
= 3.8/(1.36/√16)
= 3.8/(1.36/4)
= 3.8/0.34
= 11.18
The second picture should be the correct graph or the one which has its blue on the bottom side.
5.6-4.9=x
.7= x is the answer not .8
