Sure! Let's complete the cumulative frequency table step by step.
We'll start with the given data and fill in the missing parts:
1. For the class mark "0-10": - Frequency: 3 - Less than type Frequency: 3 (This is directly given)
2. For the class mark "10-20": - Frequency: 15 - Less than type Frequency: We know the previous cumulative frequency is 3. [tex]\[
\text{Cumulative Frequency} = 3 + 15 = 18
\][/tex] So, the less than type Frequency is 18.
3. For the class mark "20-30": - Frequency: 20 - Less than type Frequency: We know the previous cumulative frequency is 18. [tex]\[
\text{Cumulative Frequency} = 18 + 20 = 38
\][/tex] So, the less than type Frequency is 38.
4. For the class mark "30-40": - Frequency: 12 - Less than type Frequency: We know the previous cumulative frequency is 38. [tex]\[
\text{Cumulative Frequency} = 38 + 12 = 50
\][/tex] So, the less than type Frequency is 50.
Finally, we sum up all the frequencies to get the total frequency \( N \): [tex]\[
N = 3 + 15 + 20 + 12 = 50
