Whether each survey would produce the random sample or not.

Answer to Problem 8SGR
The answer is yes.
Explanation of Solution
Given:
Every tenth person coming out of a high school is asked what their favorite class is.
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.
Because each tenth student is selected so selection is random. And question is about favorite class so responses are unbiased.
Hence, the survey conducted would produce a random sample.
Therefore, the answer is yes.
