To find P(-1.1 < z < 1.4) for a standard normal distribution, we look up the z-scores in a standard normal distribution table or use a calculator. The value for z = -1.1 is approximately 0.1357, and for z = 1.4, it is approximately 0.9192. Subtracting these values gives us the probability in between: 0.9192 - 0.1357 = 0.7835.
