Answer to Question #305987 in Statistics and Probability for bugoy

Question

All but one of the following confidence intervals has a margin of error of 0.7. Which is the confidence interval with the different margin of error?

Answer 1

M. E = 0.7

C.I = $x̄ ± M. E(EE$

(20.3, 21.7) = margin of error is 0.7

(-0.5, 0.9) = margin of error is 0.7

(16, 4.6) = margin of error is not 0.7

(-6.7, - 3.3)= margin of error is 0.7

Therefore for (16, 6, 6) with margin of error is different.
