To find the margin of error for a sample proportion interval, you can use the formula:
\[ \text{Margin of Error} = \frac{(\text{Upper Limit} - \text{Lower Limit})}{2} \]
In your case, the interval is (0.62, 0.75).
- Upper Limit = 0.75
- Lower Limit = 0.62
Now calculate the margin of error:
\[ \text{Margin of Error} = \frac{(0.75 - 0.62)}{2} = \frac{0.13}{2} = 0.065 \]
Thus, the margin of error is 0.065.
