Question 865055: You are asked to construct a grouped frequency distribution table. There are to be eight class intervals with a uniform width of 5. If the first class begins with 63, then the lower class limit of the third class is ________.

You start with 63. This is given. The class width is 5. This is also given. So the first interval will go from 63 to 68 (since 63+5 = 68 or 68-63 = 5).

The second interval will start at the next integer up, which is 69. You'll add 5 to this to get 69+5=74.

The third interval will start at the next whole number above 74, which is 74+1 = 75. We can stop here, but we might as well construct the rest of the interval. This interval ends at 75+5 = 80.


Summary of what we found:

First Interval: 63-68
Second Interval: 69-74
Third Interval: 75-80


So the lower limit of the third class is 75
