The probability P(z < 1.3) for a standard normal distribution (mean = 0, standard deviation = 1) can be found using a standard normal distribution table or a calculator designed for statistical analysis. The value 0.9032 corresponds to the area under the curve to the left of z = 1.3, indicating that approximately 90.32% of the distribution falls below this value.
