Question

1. the (graph) shows the (width) interval?
2. how many students are represented in the histogram?
3. how many players scored points in november?
4. what percent of the total players scored 31 - 40 points in november?

Explanation:

Step1: Find the total number of players

From the histogram, the number of players in each interval: \(11 - 20\) has \(2\) players, \(21 - 30\) has \(1\) player, \(31 - 40\) has \(4\) players, \(41 - 50\) has \(2\) players.

$$2 + 1+4 + 2=$$

$$=9$$

Step2: Calculate the percentage of players in \(31 - 40\) interval

The formula for percentage is \(\text{Percentage}=\frac{\text{Number of players in }31 - 40}{\text{Total number of players}}\times100\)
Substitute the values: \(\frac{4}{9}\times100=\frac{400}{9}\approx44.4\%\)

Answer:

1. \(9\)
2. Approximately \(44.4\%\)
