Explanation:

Step1: Use the standard normal distribution table

The standard normal distribution table (Z - table) gives the cumulative probability \(P(Z < z)\) for a given \(z\) - score.
For \(z = 1.49\), we look up the value in the standard normal table.
In the standard normal table, we first find the row corresponding to \(z = 1.4\) and then the column corresponding to \(0.09\).
The intersection of the row \(1.4\) and column \(0.09\) in the standard normal table gives the cumulative probability.

Answer:

\(0.9319\)
