To find the percentage of rocky-soil farmers who choose to produce peppers, we can use the relative frequency formula:
\[ \text{Relative frequency} = \frac{\text{Number of farmers producing peppers}}{\text{Total number of rocky soil farmers}} \]
From the table, we see the following data related to rocky soil:
- Number of rocky-soil farmers producing peppers: 150
- Total number of rocky soil farmers: 250
We can now calculate the relative frequency:
\[ \text{Relative frequency} = \frac{150}{250} = 0.6 \]
To convert this to a percentage, we multiply by 100:
\[ 0.6 \times 100 = 60.0% \]
Thus, the percentage chance that farmers with rocky soil prefer growing peppers is 60.0%.
The correct response is: 60.0%
