Answer:
You have to make a frequency table.
Explanation:
The classes are
.320- .329
.330-.339
.340 - .349
.350 - .359
.360 - .369
Then, you have to find to find how many values would fall into the class of .340 - .349.
Classes are basically compound inequalities.
.320 ≤ x ≤.329
All x values that are less than (or equal to) .329 but greater than .320 fall into the class of
.320- .329.
Frequency is just how many numbers are in a class.
