## Number Meeting Requirement From Histogram

To estimate the number of individuals meeting a certain requirement from a histogram, we need to change frequency density into frequency using the equation
$Frequency = Frequency Density \times Interval$
.

To estimate the number of individuals taller than 100 cm from the histogram above we find:
Number of individuals between 100 cm and 105 cm

$5 \times 1=5$

Number of individuals taller than 105 cm cm

$5 \times 2.4=12$

There are 5+12=17 individuals taller than 100cm.
