Answer 1

The correct answer is B 

Answer 2

Answer: B. 5

Explanation:

• The median number of a data set is the middlemost number in the set. Also, it is the number that is halfway into the set.

The given scatter plot shows the number of chin ups and push ups completed by a sample of fourth grade students.

From the given scatter plot, we have points from 1 to 9.

The middle most number between 1 and 9 is 5.

Therefore, Median number of chin-ups for all students = 5.
