Answer:
Dependent sample: The same textbook are being compared.
Step-by-step explanation:
We are given the following in the question:
A student wants to compare textbook prices for two online bookstores.
Sample 1 from bookstore A:
$115, $43, $99, $80, $119
Sample 2 from bookstore B:
$110, $40, $99, $69, $109
Dependent and independent sample:
- Dependent samples are paired observations for same set of items.
- Independent samples are observations made on two different sets of items.
- If the values in one sample affect the observations in the other sample, then the samples are dependent.
- If the values in one sample have no effect about those of the other sample, then the samples are independent.
Thus, the given sample is dependent sample as the same textbook is being compared from two different bookstore.
