00:01 In this problem, we have been given some data which is shown over here, and this gives us the number of customers waiting for a table at 6 p .m.

00:11 For 40 consecutive saturdays at a certain restaurant.

00:14 Now, first of all, we have been asked, is this data discrete or continuous? so, recall that discrete data can take on countably many values, whereas continuous data can take on uncountably many values.

00:28 Here, the data is the number of customers.

00:32 So the number of customers waiting will either be zero or one or two or three, zero or one or two or three or so on.

00:41 So this is the set of whole numbers and the set of whole numbers is a countable set.

00:48 Because of that, this data will be discrete.

00:54 So the data is discrete.

00:55 Next, we need to construct a frequency distribution of the data.

00:59 So first of all, here we have the number of customers, and here we have the frequencies.

01:12 And the classes are given as 1 to 3, 4, 6, 7 to 9, 10 to 12, and 13 to 15.

01:25 So first of all, consider 1 to 3.

01:28 Now let's have a look at the data and see which values lie within the range.

01:33 3 and we can see that we only have this one value over here this number 3 so let's just cross that out and note that the frequency here will be 1 next we have 4 to 6 so that's going to be the values 4 5 and 6 so we can see 1 2 and we have another one over here so that's 3 and then 4 and 5 so so we have a total of five values within that range.

02:05 So from four to six, we have five.

02:08 And let's just cross these values out.

02:12 Then the next range is seven to nine.

02:14 So we have seven, eight, and nine...
