31.5%
To calculate the percentage of people who prefer cashew nuts, we first need to find the total number of people who prefer cashew nuts in both samples.
In Sample 1, 63 people prefer cashew nuts.
In Sample 2, 61 people prefer cashew nuts.
Total number of people who prefer cashew nuts = 63 (Sample 1) + 61 (Sample 2) = 124
Total number of people in both samples = 200 (Sample 1) + 200 (Sample 2) = 400
Percentage of people who prefer cashew nuts = (124 / 400) x 100% = 31.5%
Therefore, 31.5% of the people prefer cashew nuts based on the two samples.
