Answer:

[tex]Density = 1.6[/tex]

Step-by-step explanation:

The histogram is not attached; however, the given details is enough to solve the question.

Given

[tex]F = 16[/tex] --- Frequency

[tex]Interval = 25\ to\ 35[/tex]

Required

Determine the frequency density

First, we calculate the class width

[tex]Width = 35 - 25[/tex]

[tex]Width = 10[/tex]

The frequency density is:

[tex]Density = \frac{F}{Width}[/tex]

[tex]Density = \frac{16}{10}[/tex]

[tex]Density = 1.6[/tex]
