Work Step by Step
$Cumulative~relative~frequency=\frac{cumulative~frequency}{sum~of~all~frequencies}$
Cumulative relative frequency for "0-0.9" is $\frac{22}{15432}\approx0.0014$
Cumulative relative frequency for "1.0-1.9" is $\frac{44}{15432}\approx0.0029$
Cumulative relative frequency for "2.0-2.9" is $\frac{3245}{15432}\approx0.2103$
Cumulative relative frequency for "3.0-3.9" is $\frac{6577}{15432}\approx0.4262$
Cumulative relative frequency for "4.0-4.9" is $\frac{13853}{15432}\approx0.8977$
Cumulative relative frequency for "5.0-5.9" is $\frac{15283}{15432}=0,9903$
Cumulative relative frequency for "6.0-6.9" is $\frac{15413}{15432}\approx0.9988$
Cumulative relative frequency for "7.0-7.9" is $\frac{15431}{15432}\approx0.9999$
Cumulative relative frequency for "8.0-8.9" is $\frac{15432}{15432}=1$
