The following data describes percentage of satisfied customers at Burger Barn. Complete the frequency table for this data.

86.9,93.0,89.3,90.3,96.4,94.1,82.1,88.9,95.1,80.1,83.6,91.5,90.3,89.7,93.2,91.6,88.4,85.7
Determine the frequency of 79.0–82.9

To complete the frequency table, we first need to count how many data points fall within the given range, 79.0–82.9.

Here is the data set again:

\[
86.9, 93.0, 89.3, 90.3, 96.4, 94.1, 82.1, 88.9, 95.1, 80.1, 83.6, 91.5, 90.3, 89.7, 93.2, 91.6, 88.4, 85.7
\]

To find the frequency for 79.0–82.9, let's identify how many values fall in this range.

Values in the range of 79.0–82.9:
- 80.1
- 82.1

These two values fall within the range 79.0–82.9.
