Question

PLEASE HELP WILL MARK BRAINLIEST AND GIVE 50 POINTS

Answer 1

Answer:

The correct option is;

e. 2500

Step-by-step explanation:

The formula for sample size is given by the following formula;

$n = \dfrac{z^2 \times \hat p(1 - \hat p)}{\epsilon ^2}$

At 95%, z = 1.96

ε = Margin of error = 0.02 = 2%

Finding the sample size, n, given only the margin of error is by the following formula;

Margin of error = 100/√n

Therefore, we have;

2 = 100/√n

√n = 100/2 = 50

n = 50² = 2500

Therefore, the correct option is e. 2500.
