For a sample proportion interval (0.62, 0.75), what is the margin of error?

1 answer

To find the margin of error for the sample proportion interval (0.62, 0.75), you can use the formula for the margin of error, which is half the width of the interval.

  1. First, find the width of the interval: \[ \text{Width} = \text{Upper limit} - \text{Lower limit} = 0.75 - 0.62 = 0.13 \]

  2. Next, divide the width by 2 to find the margin of error: \[ \text{Margin of Error} = \frac{\text{Width}}{2} = \frac{0.13}{2} = 0.065 \]

So, the margin of error for the sample proportion interval (0.62, 0.75) is 0.065.
