Answer 1

C

Explanation:

Answer 2

In constructing a frequency table, first you'll need to arrange your data from lowest to highest and solve for the following: range, class width, and class size.

Range: Highest Value - Lowest Value in the data set.
= 18 - 0 = 0
Class Width: Square root of the total number of data. In the data set, we have 14 numbers. This is the number of classes.
= sqrt (14) = 3.7 or 4
Class Size: Range divided by Class Width.
=18/4 = 4.5 or 5. There should be five numbers inside each class.

The Frequency Table is below.

Eagles | Frequency
0-4 4
5-9 5
10-14 3
15-19 2
