To find: The conditions that are not satisfied to perform a paired t -test.
Expert Solution & Answer
Answer to Problem 103E
Randomization condition is not fulfilled.
Explanation of Solution
Given:
The dot plot and output are:
Concept used:
Following are the main requirements for the paired t- test:
- The samples taken from the population are simple random samples.
- The
size of the sample must be at least 30. - Population must be at least 10% greater than the sample size.
In this case,
- Data is gathered only on Friday and it is not possible that everyone goes out for the shopping on Friday. Thus, the sample is not random.
- The sample size is 45 which is above 30. Thus, normality condition is fulfilled.
- Sample size of 45 is lower than the 10% of the size of the population.
Thus, the correct option is (a).
