How would you determine the frequency for a class interval using a frequency polygon?

A frequency polygon for employee ages has a peak at midpoint 35 and a long tail to the left. What does this suggest about the age distribution?

On a frequency polygon, what does the y-coordinate of each plotted point represent?

What is a frequency distribution?

If a frequency polygon shows a point at (60, 15), what does this mean in the context of class intervals?

In a histogram, what does the height of each bar represent?

Which of the following best describes a frequency polygon?

Given the following class intervals and frequencies for monthly expenses: \(0-\)499 (5), \(500-\)999 (12), \(1000-\)1499 (9), \(1500-\)1999 (4), construct the list of points to plot for a frequency polygon.

Why is a frequency polygon not the same as a line graph?
