Answer:
If we solve for k we can do this:
So then we have at last 75% of the data withitn two deviations from the mean so the limits are:
Step-by-step explanation:
We don't know the distribution for the scores. But we know the following properties:
For this case we can use the Chebysev theorem who states that "At least of the values lies between
and
"
And we need the boundaries on which we expect at least 75% of the scores. If we use the Chebysev rule we have this:

Answer:
Step-by-step explanation:
Given that a researcher is using a repeated-measures design to test for mean differences among four treatment conditions.
The data for this study consist of 10 scores in each treatment.
We have to find the total subjects who participated in the study.
Each treatment has 10 scores
No of treatments = 4
Hence subjects participated in the study
= no of treatment x no of subjects
=
