To find the overall percentage of people who prefer cashew nuts based on the two samples, we first need to determine the total number of people who prefer cashew nuts from both samples and then calculate the percentage out of the total number of people surveyed.
From the data provided:
- Sample 1: 63 people prefer cashew nuts
- Sample 2: 61 people prefer cashew nuts
Now, we calculate the total number of people who prefer cashew nuts:
\[ \text{Total preferring cashew} = 63 + 61 = 124 \]
The total number of people surveyed is the sum of both samples:
\[ \text{Total surveyed} = 200 + 200 = 400 \]
Now we can calculate the percentage of people who prefer cashew nuts:
\[ \text{Percentage preferring cashew} = \left( \frac{124}{400} \right) \times 100 \]
Calculating this gives:
\[ \text{Percentage preferring cashew} = 31% \]
Thus, the answer is:
31%
