In the given question, we are having a frequency distribution table and this table is for this force for the math test.
00:22
And we need to find the class boundaries for the interval which is 50 to 59.
00:29
So now let's see the table.
00:32
Here we have our table given into the question.
00:35
So the scores are 50 to 59 and we have number of students as students.
00:39
Then 60 to 69 number of students are 4, then 70 to 79 number of students are 6.
00:46
And 80 to 89 number of students are 15, then 90 to 99 number of students are 5.
00:54
So this is our data.
00:57
So here, as we can see, our class intervals are not continuous as we have our post term as 50.
01:04
Upper limit is 59.
01:07
So the next interval is not starting with 59.
01:10
So, what we do for these kind of data, we will minus 0 .5 from lower limit minus 0 .5.
01:21
And in upper limit, we will add 0 .5...
