$1.14$ Table $1.13$ shows the amount, in inches, of annual rainfall in a sample of towns.

From the table $1.13$, find the percentage of rainfall that is less than $9.01$ inches.

Percentage of rain less than $9.01$ inches

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

The total frequency is$50$

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

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

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

Hence, it is proved.
