Question
Chapter 10, Problem 1FP
To determine
Distinguish related samples from independent samples.
Expert Solution & Answer
Answer to Problem 1FP
In related samples the participants are either matched or observed twice whereas in independent samples the participants of each group are different.
Explanation of Solution
Justification: In independent samples test, the participants in each of the group are different that is the participants are not related to each other. In related samples the participants of each group are related. The participants of each group are matched in common characteristics or each of the participants is measured more than once in the study.

difference?
In order to find probability, you can use this formula in Microsoft Excel:
The best way to understand and solve these problems is by first drawing a bell curve and marking key points such as x, the mean, and the areas of interest. Once marked on the bell curve, figure out what calculations are needed to find the area of interest.
=NORM.DIST(x, Mean, Standard Dev., TRUE).
When the question mentions “greater than” you may have to subtract your answer from 1.
When the question mentions “between (two values)”, you need to do separate calculation for both values and then subtract their results to get the answer.

Compute the probability of a value between 44.0 and 55.0.
(The question requires finding probability value between 44 and 55. Solve it in 3 steps.
In the first step, use the above formula and x = 44, calculate probability value.
In the second step repeat the first step with the only difference that x=55.
In the third step, subtract the answer of the first part from the…
