Question: 1.7 APPLET Choosing Classes in a Histogram. The data set menu that accompanies the One-Variable Statistical Calculator applet includes the data on the percent minorities

1.7 APPLET Choosing Classes in a Histogram. The data set menu that accompanies the One-Variable Statistical Calculator applet includes the data on the percent minorities between the ages of 18 and 34 in the states from Table 1.2. Choose these data, then click on the "Histogram" tab to see a histogram. MINORITY

(a) How many classes does the applet choose to use? (You can click on the graph outside the bars to get a count of classes.)

(b) Click on the graph and drag to the left. What is the smallest number of classes you can get? What are the lower and upper bounds of each class? (Click on the bar to find out.) Make a rough sketch of this histogram.

(c) Click and drag to the right. What is the greatest number of classes you can get? How many observations does the largest class have?

(d) You see that the choice of classes changes the appearance of a histogram. Drag back and forth until you get the histogram that you think best displays the distribution. How many classes did you use? Why do you think this is best?
