Answer

Examining the table given, the truth of the statements can be identified.

Looking at option I. No class is offered in less than one-third of the schools.

It is seen that Sculpting is offered in 13% of the schools which is less than 33% therefore sculpting is offered in less than one-third of the schools thus making the statement false.

Looking at option II. Every school in the district offers either Gym or an Art class.

The table states that 5 schools offer Gym and a total of three schools offer Art (Painting or Sculpting). This makes a total of 8 schools but it is unknown if there are 8 different school or if the 5 schools that have gym also have an art class. Therefore this statement is false.

Looking at option III. Math is an academic class that all schools in Dawn County offer.

The table shows that the % of schools offering Math is 100% therefore this statement is true.
