The table provided shows frequencies for different numbers of movies, and it requires calculations for both relative frequency and cumulative relative frequency. Let's proceed step by step.

Step 1: Calculate the Total Frequency

The total frequency is the sum of all individual frequencies: $5 + 10 + 5 + 4 + 1 = 25$ This total is important for determining the relative frequency.

Step 2: Calculate the Relative Frequency

Relative frequency is calculated as the frequency for each category divided by the total frequency. Let's compute it for each category:

• For 0 movies: $\frac{5}{25} = 0.2$
• For 1 movie: $\frac{10}{25} = 0.4$
• For 2 movies: $\frac{5}{25} = 0.2$
• For 3 movies: $\frac{4}{25} = 0.16$
• For 4 movies: $\frac{1}{25} = 0.04$

Step 3: Calculate the Cumulative Relative Frequency

Cumulative relative frequency is calculated by adding up the relative frequencies progressively. Let's compute it:

• For 0 movies: $0.2$ (same as the relative frequency)
• For 1 movie: $0.2 + 0.4 = 0.6$
• For 2 movies: $0.6 + 0.2 = 0.8$
• For 3 movies: $0.8 + 0.16 = 0.96$
• For 4 movies: $0.96 + 0.04 = 1.00$

Would you like more details or any clarifications?

Here are 5 related questions:

1. What does the cumulative relative frequency represent?
2. How do we interpret a relative frequency of 0.4?
3. How would the table change if the frequency for 1 movie increased?
4. What happens to cumulative relative frequency if the total frequency is underestimated?
5. How could this data be represented in a graph?

Tip: Always check that the cumulative relative frequency sums to 1 (or very close to 1 due to rounding) to ensure calculations are correct.
