Answer 1

To find the correct cumulative relative frequencies, we begin by calculating the cumulative relative frequency using the relative frequencies provided.

The relative frequencies for each class are as follows:
- \(R_0 = 0.07\)
- \(R_1 = 0.24\)
- \(R_2 = 0.18\)
- \(R_3 = 0.34\)
- \(R_4 = 0.17\)

Now, let's calculate the cumulative relative frequency step by step:

1. For \(x = 0\):
- Cumulative Relative Frequency \(C_0 = R_0 = 0.07\)

2. For \(x = 1\):
- Cumulative Relative Frequency \(C_1 = C_0 + R_1 = 0.07 + 0.24 = 0.31\)

3. For \(x = 2\):
- Cumulative Relative Frequency \(C_2 = C_1 + R_2 = 0.31 + 0.18 = 0.49\)

4. For \(x = 3\):
- Cumulative Relative Frequency \(C_3 = C_2 + R_3 = 0.49 + 0.34 = 0.83\)

5. For \(x = 4\):
- Cumulative Relative Frequency \(C_4 = C_3 + R_4 = 0.83 + 0.17 = 1.00\)

Now, compiling this information gives us the following cumulative relative frequencies:
- For \(x = 0\): \(0.07\)
- For \(x = 1\): \(0.31\)
- For \(x = 2\): \(0.49\)
- For \(x = 3\): \(0.83\)
- For \(x = 4\): \(1.00\)

Now, we compare our calculations with the options given. The correct table of cumulative relative frequencies is:

```
upper x Frequency Relative Frequency Cumulative Relative Frequency
0 35 0.07 0.07
1 120 0.24 0.31
2 90 0.18 0.49
3 170 0.34 0.83
4 85 0.17 1.00
```

Thus, the correct response is the second option displayed in the problem statement.
