Solution Steps

To find the range of a set of data, you need to determine the difference between the largest and the smallest values in the data set.

Step 1: Identify the Largest and Smallest Values

To find the range of a data set, we first need to identify the largest and smallest values in the set. Given the data set \([3, 7, 2, 9, 4]\):

  • The largest value is \(9\).
  • The smallest value is \(2\).
Step 2: Calculate the Range

The range is calculated by finding the difference between the largest and smallest values: \[ \text{Range} = \text{Largest value} - \text{Smallest value} = 9 - 2 = 7 \]

Final Answer

The range of the data set is: \[ \boxed{7} \]

Read the excerpt from Midsummer by Derek Walcott. I was there to add some color to the British theater. "But the blacks can't do Shakespeare, they have no experience. Based on the excerpt, what is the speaker's perspective on British theater? The speaker feels that most people are familiar with Shakespeare. The speaker feels that British theater is not inclusive of all races. The speaker feels that most actors need more experiencé. The speaker feels that Shakespeare is overrated in England.
