Answer:
The conclusion about p using an absolute value inequality is

Step-by-step explanation:
From the question we are told that
The sample proportion is 
The margin of error is 
The confidence interval is mathematically represented as

=> 
=> 
If a=0, then the denominator is equal to 0. Since you cannot divide by zero, you are not allowed to do this.

Luke: 1 practice 1 lap, 2 practices 2 laps, 3 practices 3 laps, 4 practices 4 laps
Alex: 1 practice 3 laps, 2 practices 6 laps, 3 practices 9 laps, 4 practices 12 laps
Luke ran 3 laps for 3 practices, and Alex ran 9 laps for 3 practices.
