Final answer:
To find the indicated probability using the standard normal distribution, use the standard normal distribution table or a calculator.
Step-by-step explanation:
To find the indicated probability using the standard normal distribution, we need to use the standard normal distribution table or a calculator. (a) P(Z < 1.16) is the area under the curve to the left of 1.16, which can be found to be approximately 0.8764. (b) P(Z < -0.18) is the area under the curve to the left of -0.18, which can be found to be approximately 0.4286.
