$Cumulative~relative~frequency=\frac{cumulative~frequency}{sum~of~all~frequencies}$
Total (sum of all frequencies): 35 stocks for each industry.
- Goods Stocks:
Cumulative relative frequency for"-20.00 -10.01" is $\frac{1}{35}\approx0.0286$
Cumulative relative frequency for"-10.00 -0.01" is $\frac{1+5}{35}\approx0.1714$
Cumulative relative frequency for "0.00 9.99" is $\frac{1+5+15}{35}=0.6000$
Cumulative relative frequency for "10.00 19.99" is $\frac{1+5+15+10}{35}\approx0.8857$
Cumulative relative frequency for "20.00 29.99" is $\frac{1+5+15+10+3}{35}\approx0.9714$
Cumulative relative frequency for "30.00 39.99" is $\frac{1+5+15+10+3+1}{35}=1$
- Energy Stocks:
Cumulative relative frequency for"-20.00 -10.01" is $\frac{0}{35}=0$
Cumulative relative frequency for"-10.00 -0.01" is $\frac{0+5}{35}\approx0.1429$
Cumulative relative frequency for "0.00 9.99" is $\frac{0+5+16}{35}=0.6000$
Cumulative relative frequency for "10.00 19.99" is $\frac{0+5+16+12}{35}\approx0.9429$
Cumulative relative frequency for "20.00 29.99" is $\frac{0+5+16+12+2}{35}=1$
Cumulative relative frequency for "30.00 39.99" is $\frac{0+5+16+12+2+0}{35}=1$
