00:01 In this problem, we're analyzing 30 companies in the dow jones industrial average.

00:06 The first thing we're asked to do is find the highest price and the lowest price per share of the 30 companies.

00:12 So what you need to do is find the largest number and the smallest number in the data set.

00:18 Once you do that, you should find that the highest price per share is $107.

00:23 And our lowest price per share is $11.

00:26 Next, we're asked to find the frequency distribution.

00:31 I'm using a class width of 10.

00:34 So since we're dealing with money, i'm going to start with $0 to $9.

00:40 Then our next class will be $10 to $19.

00:44 So you just pick up right where you left off.

00:47 And then we're going to continue this pattern of creating classes until we get to a class that includes our highest price per share, $107.

00:58 So ultimately that's going to look like this and our last class is $100 to $109.

01:05 Then to actually create the frequency distribution, we're going to go through our data set and count how many companies fall within each class.

01:15 So we should already know because our lowest price per share was $11 that there's going to be zero companies that fall within the zero to nine price per share class.

01:27 So then 10 to 19, you'll go through and count all of the companies that fall within this class, and you should get five total companies.

01:38 Then from 20 to 29, we should get 10 companies that fall into this class.

01:45 30 to 39 has three companies, 40 to 49 has two, 50 to 59 has two, 50 to 59 has six companies, 60 to 69 has two, 70 to 79 has one, and then there are zero companies that have a price per share from 80 to 99 dollars, and then our last class has just one company.

02:13 So then we're going to use this information to help us create the histogram in part c.

02:19 So for our histogram, we want to make sure we have a title, and then that our both axes are labeled.

02:27 So our x -axis is going to be our price per share.

02:31 This information is coming from the classes that we created.

02:34 So this part is zero to nine, second class, 10 to 19, and so on.

02:41 Then our y -axis is our frequency, or how many companies, fall within each class.

02:47 So to create the histogram, we're going to draw rectangles.

02:52 So this first class doesn't have any rectangles because there were zero companies.

02:58 The second class, we're going to draw a rectangle until we get to five on the y -axis.

03:06 And make sure when you draw your rectangle that you are using the entire width of the class.

03:13 Then for this third class, 20 to 29, our rectangle is going to go from our x -axis all the way to 10.

03:25 And again, making sure that your width is the entire class.

03:29 So you'll continue this process until you've included all of the companies...
