Percentage of rain less than $9.01$ inches

See the step by step solution

## Step 1: Given Information

Frequency less than $9.01=6+7+15=28$

The total frequency is$50$

## step 2: Calculation

The percentage of rainfall is less than $9.01$ inches is $56%$

$Percent=\frac{Frequencylessthan9.01}{TotalFrequency}×100\phantom{\rule{0ex}{0ex}}Percent=\frac{6+7+15}{50}×100\phantom{\rule{0ex}{0ex}}Percent=56%$

The percentage of rainfall is less than inches is $56%$

Hence, it is proved.
