Verified step by step guidance

1. Step 1: Begin by identifying the total number of students surveyed. To do this, sum up the frequencies for all cake flavors: Vanilla (32), Chocolate (55), Marble (34), and Other (49). Use the formula: Total = 32 + 55 + 34 + 49.
2. Step 2: Calculate the proportion of students who prefer vanilla cake. Divide the frequency of vanilla cake (32) by the total number of students obtained in Step 1. Use the formula: Proportion = Frequency of Vanilla / Total.
3. Step 3: Convert the proportion obtained in Step 2 into a percentage. Multiply the proportion by 100 to express it as a percentage. Use the formula: Percentage = Proportion × 100.
4. Step 4: Verify your calculation by ensuring the sum of percentages for all cake flavors equals approximately 100%. This step helps confirm the accuracy of your work.
5. Step 5: Use the percentage calculated in Step 3 to create the pie chart segment for vanilla cake. Label the segment with the percentage value and ensure the chart visually represents the proportions of all cake preferences.
