The data below gives the number of books that 15 students  checked out of the school library in  one month. make a frequency table of the data. 0, 3, 2, 3, 2, 1, 1, 0, 1, 2, 5, 1, 2, 3, 1

See the explanation below.

A frequency table is a way to organize data. We create bins (intervals) to collect the data. Then, we give the frequency (number) of data values in each interval.

Here is an example of how you could sort this data.

Interval:     Frequency:
0 - 1                  7
2 - 3                  7
4 - 5                  1

a. Since 10 out of 70 had a tag we can write the ratio 10:70. We need to solve for x in 90:x. x = 630 so the answer is 630.

b. An assumption he could have made is that the number of deer that had a tag and the total amount of deer were directly proportional.
