See the picture.
Work Step by Step
$Cumulative~relative~frequency=\frac{cumulative~frequency}{sum~of~all~frequencies}$
Total (sum of all frequencies): $22+68+15+5+0+0+0+1=111$ community colleges.
Cumulative relative frequency for "775-799" is $\frac{22}{111}\approx0.1982$
Cumulative relative frequency for "800-824" is $\frac{90}{111}\approx0.8108$
Cumulative relative frequency for "825-849" is $\frac{105}{111}\approx0.9459$
Cumulative relative frequency for "850-874" is $\frac{110}{111}\approx0.9910$
Cumulative relative frequency for "875-899" is $\frac{110}{111}\approx0.9910$
Cumulative relative frequency for "900-924" is $\frac{110}{111}\approx0.9910$
Cumulative relative frequency for "925-949" is $\frac{110}{111}\approx0.9910$
Cumulative relative frequency for "950-974" is $\frac{111}{111}=1$
