See the picture.
Work Step by Step
$Cumulative~relative~frequency=\frac{cumulative~frequency}{sum~of~all~frequencies}$
Total (sum of all frequencies): 34 cookies.
The cumulative relative frequency for "2.2000-2.2399" is $\frac{5}{34}\approx0.1471$
The cumulative relative frequency for "2.2400-2.2799" is $\frac{16}{34}\approx0.4706$
The cumulative relative frequency for "2.2800-2.3199" is $\frac{27}{34}\approx0.7941$
The cumulative relative frequency for "2.3200-2.3599" is $\frac{33}{34}\approx0.9706$
The cumulative relative frequency for "2.3600-2.3999" is $\frac{34}{34}=1$
