c 31%
To find the percentage of people who prefer cashew nuts, we add up the number of people in both samples who prefer cashew nuts:
63 (from Sample 1) + 61 (from Sample 2) = 124
Then, we divide this total by the total number of people surveyed in both samples (400) and multiply by 100 to find the percentage:
(124/400) x 100 = 31%
.The data from two random samples of 200 people regarding their favorite nuts is shown in the following table.
