Question
Let \( X_1, X_2, \ldots, X_{100} \) be 100 independent and identically distributed continuous random variables with mean 

\[
\mu 
\]

= 37 and variance 

\[
\sigma^2
\]

= 25.

Let \( S = X_1 + X_2 + \ldots + X_{100} \). Use the Central Limit Theorem to approximate the probability that \( S \) is less than 3800, i.e., \(\text{P}(S < 3800)\). Enter your answer to 4 decimal places.

**Hint:** Calculate the mean 

\[
\mu_S
\]

and variance 

\[
\sigma^2_S
\]

of \( S \). By the Central Limit Theorem, \( S \) is approximately normally distributed with mean 

\[
\mu_S
\]

and variance 

\[
\sigma^2_S
\]

when the sample size is larger than 30. In other words, standardization of \( S \) leads to

\[
\frac{S - \mu_S}{\sigma_S} \approx Z
\]
