In problem 10, we have the salary of 36 in belwees of a small company, 36 in bullies, and it's in thousands of dollars.

You want to make a histogram using specific class boundaries.
00:22
The class boundaries, you have here the class, and the boundaries is from 53 .5 to 99 .5, then 99 .5 to 145.
00:39
Then 145 .5 to 191 .5 then from 191 .5 to 237 .5.
00:57
And finally, 237 .5 to 283 .5.
01:06
We want to calculate the frequency.
01:11
We can calculate the frequency by counting the numbers that lie between the class boundaries for each class for the first class from 53 .5 to 99 .5 thousand dollars we can find 35 counts most of the employees lie in this category in this class and the second class zero zero and we can find only one number that lie in the final class the last number then its count is 1.
01:53
The total must be 36.
01:58
To make a histogram for this table, in the x -axis, we put the class boundaries, and in the y -axis we put the frequency.
02:08
The maximum is 35, and we can see here 0.
02:16
And for the class boundaries that starts at 53 .5, then we have 99 .5, 145 then 191 .5 then 237 .5 and finally 283 .5 the first class has a bound has a frequency of 35 then start here by 35 the second is 0 0 until we have only one here for the final class this is the histogram.
03:03
We can see that there is something wrong...
