Answer to Problem 7SGR
The answer is yes.
Explanation of Solution
Given:
Every tenth shopper coming out of a hardware store is surveyed to determine his or her satisfaction with the store.
In the random sample, every part of population will have the same chance to get selected.
Which means the value of the probability will be equal for each part.
When the response are not in random way and every person is not same then it is not known as the random sample.
Therefore, yes, it is the random sample.
Where, each tenth person is getting selected which states that the selection is random, hence the obtained responses are not biased.
Thus, the conducted survey will generate the random sample.
Hence, the answer is yes.
