Question
Chapter 1, Problem 1.41RE
a)
To determine
To give the list of the question of interest.
a)
Expert Solution
Explanation of Solution
Given:
The pie chart shows the percentage of allowance received a week for the children between aged 5 to 12. Therefore, the question becomes, “How much allowance do you receive a week?”
b)
To determine
To identify whether the observational study or experimental study.
b)
Expert Solution
Answer to Problem 1.41RE
This is anobservation study.
Explanation of Solution
Given:
First need to understand about the experimental study and observational study:
Experimental study: Assigning people or things to groups and applying some treatment to one group, while the other group does not receive the treatment.
Observation study: In an observational study, measure or survey members of a sample without trying to affect them.
This study is an observation study. This survey can be done by just asking a question to the children or their parents.
c)
To determine
To find individuals and variables.
c)
Expert Solution
Answer to Problem 1.41RE
An individual is child aged between 5 to 12.
Explanation of Solution
Given:
First need to know what is mean by individual.
Individuals are the objects described by the set of the data. Therefore, it is regarding the children aged between 5 to 12. Hence, individual is child aged between 5 to 12. Variables are allowance money.
d)
To determine
To explain why four percentages are makes 100%
d)
Expert Solution
Answer to Problem 1.41RE
Explanation of Solution
Given:
As these four percentages are rounded percentage. They are not exact percentage. Therefore, its sum is around 99%.

- According to an economist from a financial company, the average expenditures on "furniture and household appliances" have been lower for households in the Montreal area than those in the Quebec region. A random sample of 14 households from the Montreal region and 16 households from the Quebec region was taken, providing the following data regarding expenditures in this economic sector. It is assumed that the data from each population are distributed normally. We are interested in knowing if the variances of the populations are equal. a) Perform the appropriate hypothesis test on two variances at a significance level of 1%.
