To find \( P(X < -2.27) \) where \( X \) is a standard normal random variable, we can use the cumulative distribution function (CDF) for a standard normal distribution.
Using standard normal distribution tables or calculators, we can find \( P(X < -2.27) \).
Using a standard normal distribution table or a calculator:
\[
P(X < -2.27) \approx 0.0116
\]
Thus, the probability \( P(X < -2.27) \) is approximately \( 0.0116 \).
