A wildlife biologist tracks the number of wolves in a particular region. Data for 15 months is shown. Use the
data to make a frequency table with intervals.
15, 19, 24, 28, 26, 29, 17, 16, 17, 14, 22, 20, 18, 27, 27

Answer 1

To create a frequency table with intervals for the given data set, we can determine the range, the number of intervals, the width of each interval, and then create the intervals and count the frequency of data points in each interval.

Step-by-step explanation:

A frequency table with intervals can be created by grouping the data into ranges or intervals and counting the number of data points that fall into each interval. To create the frequency table for the given data set, we can start by determining the range of the data, which is the difference between the largest and smallest values. In this case, the range is 15 (29 - 14).

Next, we can determine the number of intervals or groups we want to use. It is common to use 5 to 10 intervals. For simplicity, let's use 5 intervals.

The width of each interval can be calculated by dividing the range by the number of intervals. In this case, the width is 3 (15 / 5).

We can then create the intervals by starting with the smallest value and adding the width to find the endpoints of each interval. The frequency can be determined by counting the number of data points that fall into each interval.

Using these steps, the frequency table with intervals for the given data set can be:
