Short Answer

Expert verified

The probability that the sum of the $100$ values falls between $P (3900 < Σ X < 3910) = 0.5433$ .

Step by step solution

Given Information

The researcher randomly selects a sample $(n)$ is $100$ .

Explanation

To find the probability that the sum of the $100$ values falls between $P (3900 < Σ X < 3910)$ : $= P (\frac{3900 - 3901}{5} < Z < \frac{3910 - 3901}{5})$

$= P (- 0.2 < Z < 1.8)$

$= P (Z < 1.8) - Pr (Z < - 0.2)$

$= 0.9641 - 0.4208$

$= 0.5433$
