According to the given table, there are 6 classes. We have to find the amplitude of each class as follows

[tex]A=\frac{1486-809}{6}=113[/tex]

We use this amplitude to find the limits of the classes.

[tex]\begin{gathered} 809+113=922 \\ 922+113=1035 \\ 1035+113=1148 \\ 1148+113=1261 \\ 1261+113=1374 \\ 1374+113=1487 \end{gathered}[/tex]

So, the intervals are shown in the image below

Now, we determine the frequency of each interval. Remember that the frequency refers to the numbers that fall into an interval.

The image below shows the frequency column.
