Question
Chapter 13, Problem 47UP
To determine
Explain whether the specified statement is true or false.
Expert Solution & Answer
Answer to Problem 47UP
False.
Explanation of Solution
It is given that if the null hypothesis is rejected then there is a causal relationship between the two categorical variables.
In chi-square test of independence the hypotheses are given below:
Here, if the null hypothesis is rejected then it can be said that the two variables are dependent.
If in a relationship, the occurrence of the 1st variable causes the 2nd variable, it can be said that there is a causal relationship between the two variables.
Therefore, it is clear that if two variables are dependent, that does not imply about causal relationship between the two variables.
Therefore, the statement is false.

Bob and Teresa each collect their own samples to test the same hypothesis. Bob’s p-value turns out to be 0.05, and Teresa’s turns out to be 0.01.
Why don’t Bob and Teresa get the same p-values?
Who has stronger evidence against the null hypothesis: Bob or Teresa?

1. State if you agree or disagree with the choices made for additional analysis
that can be done beyond the frequency table.
2. Choose a measure of central tendency (mean, median, mode) that you
would like to compute with the data beyond the frequency table. Complete
either a or b below.
a. Explain how that analysis can help you understand the data better.
b. If you are currently unable to do that analysis, what do you think you
could do to make it possible? If you do not think you can do
anything, explain why it is not possible.
