To find the percentage of farmers with rocky soil who prefer to grow peppers, we need to calculate the proportion of rocky-soil farmers who grow peppers relative to the total number of rocky-soil farmers.
From the table:
- Farmers with rocky soil growing peppers: 150
- Total farmers with rocky soil: 250
Now, we calculate the proportion:
\[ \text{Proportion of rocky-soil farmers growing peppers} = \frac{\text{Farmers with rocky soil growing peppers}}{\text{Total rocky-soil farmers}} = \frac{150}{250} \]
Calculating the fraction:
\[ \frac{150}{250} = 0.6 \]
Now, to convert this fraction into a percentage:
\[ 0.6 \times 100 = 60.0% \]
Thus, the percentage chance that farmers with rocky soil prefer growing peppers is 60.0%.
The correct response is: 60.0%.
