Using the traditional formula, a 95% CI for p1 − p2 is to be constructed based on equal sample sizes from the two populations. F

inn [45]

Answer:

Step-by-step explanation:

Given:

Width = 0.4

Let's take the z value of 95% which is = 1.96

Let's assume population proportion p1 and p2 = 0.5

For margin of error E, the relation between the width and margin of error is 2E.

i.e 2E = 0.4

E = 0.2

To find the sample size, n, let's use the formula :

$n= \frac{z^2*(p_1(1-p_1) + p_2(1-p_2))}{E^2}$

$= \frac{1.96^2(0.5(1-0.5)+0.5(1-0.5))}{0.2^2}$

= 48.02

≈ 49
