Answer:
A nonresponse might lead to a bias in the study due to the fact that the counselor may assume that those who did not reply to the email may have tried alcohol and they didn't want him(the counselor) to know.
Step-by-step explanation:
In statistical research, a bias is said to occur when systematic errors are introduced into sampling or testing by selecting or favoring one outcome over other outcomes.
Now, applying that definition to this question, we can say that a nonresponse might lead to a bias in the study due to the fact that the counselor may assume that those who did not reply to the email may have tried alcohol and they didn't want him(the counselor) to know.

Step-by-step explanation:
It is correct trust me.
30 min: 60min-30min= 30 min and 30 min is half an hour. So since 30 min is half an hour you divide 4 by 2 and get 2 miles.
45 min: 60min-45min= 15 min. 15 is one quarter of an hour so, since you are going 4mph. So you do 4mph divided by another for because there are four quarters in one hour, which gives you one mile. Then you 1 mile 3 times because 15+15+15=45. So the answer is 3 miles.
2 hours: 2x4= 8 miles
3 hours: 3 hours x 4mph= 12 miles
