To calculate the percentage of people who prefer cashew nuts based on the two samples, we first need to find the total number of people who prefer cashew nuts from both samples and then divide by the total number of people surveyed.
From the table:
- Sample 1: 63 people prefer cashew nuts
- Sample 2: 61 people prefer cashew nuts
Total number of people who prefer cashew nuts = 63 + 61 = 124
Total number of people surveyed = 200 (Sample 1) + 200 (Sample 2) = 400
Now, to find the percentage of people who prefer cashew nuts:
\[ \text{Percentage} = \left( \frac{\text{Number of people who prefer cashews}}{\text{Total number of people surveyed}} \right) \times 100 \]
\[ \text{Percentage} = \left( \frac{124}{400} \right) \times 100 = 31% \]
Thus, the percentage of people who prefer cashew nuts is 31%.
