The following confidence interval is obtained for a population proportion,
p: 0.620 < p < 0.658
Use these confidence interval limits to find the margin of error, E.

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
