Explanation:

Step1: Find total frequency (a)

Sum all frequencies: $4 + 2+3 + 12+7+2+4+20+5+7+2+12=80$.

Step2: Calculate relative frequency (b)

Relative frequency = $\frac{\text{Frequency}}{\text{Total frequency}}$. For the fare of $\$999$, relative frequency $b=\frac{3}{80}= 0.038$.

Step3: Calculate relative frequency (c)

For the fare of $\$1157$, relative frequency $c=\frac{20}{80}=0.250$.

Step4: Calculate cumulative frequency (d)

Cumulative frequency is the sum of previous frequencies. For the fare of $\$1053$, cumulative frequency $d = 21+7=28$.

Step5: Calculate cumulative frequency (e)

For the fare of $\$1209$, cumulative frequency $e=59 + 7=66$.

Step6: Calculate relative - cumulative frequency (f)

Relative - cumulative frequency for the fare of $\$1133$ is $\frac{34}{80}=0.425$.

Step7: Calculate relative - cumulative frequency (g)

Relative - cumulative frequency for the last row (total) is $1.000$.

Answer:

a. 80
b. 0.038
c. 0.250
d. 28
e. 66
f. 0.425
g. 1.000
