Answer:
The true statement is:
<u>A) Over half of the bike owners live near a pool. </u>
Step-by-step explanation:
See the attached table
According to the data of the table, we will check which statement is true.
A) Over half of the bike owners live near a pool.
The number of the bike owners = 8 + 7 = 15
The bike owners live near a pool = 8
The percentage of the bike owners live near a pool to all the bike owners= 8/15 = 0.533 > 0.5
<u>The statement is true.</u>
B) Less than 55% of his classmates live near a pool.
The number of classmates = 30
The number of classmates live near a pool = 8 + 10 = 18
The number of classmates live near a pool to all
classmates = 18/30 = 0.6 = 60% > 55%
<u>The statement is wrong.</u>
<u></u>
C) About 50% of his classmates don't live near a pool.
Don't live near a pool = live near a pool
So, the same explanation of statement B
<u>The statement is wrong.</u>
<u></u>
D) 2/3 of his classmates that live near a pool don't own a bike.
The number of classmates live near a pool = 8 + 10 = 18
The number of classmates live near a pool and don't own a bike = 10
The percentage of classmates live near a pool and don't own a bike to classmates live near a pool = 10/18 = 0.556 < 2/3
<u>The statement is wrong.</u>
