Question

Find the margin of error given values of C, s, and n. Round to the nearest tenth as needed. C = 0.80 S = 6 n = 8

Answer 1

Therefore, the margin of error, rounded to the nearest tenth, is approximately 1.7.

Explanation:

To find the margin of error, we need to use the formula:

Margin of Error = C * (s / sqrt(n))

Given values:

C = 0.80

s = 6

n = 8

Substituting these values into the formula:

Margin of Error = 0.80 * (6 / sqrt(8))

Calculating the square root of 8:

sqrt(8) ≈ 2.8284

Margin of Error = 0.80 * (6 / 2.8284)

Dividing 6 by 2.8284:

6 / 2.8284 ≈ 2.1213

Margin of Error = 0.80 * 2.1213

Calculating the product:

0.80 * 2.1213 ≈ 1.697
