The true statement is:

A) Over half of the bike owners live near a pool.

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

The statement is true.

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%

The statement is wrong.

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

The statement is wrong.

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

The statement is wrong.
