Quizplus · Accepted Answer

Using a standard normal distribution table, we find the area to the left of -0.31 is 0.3783. This represents the probability that z is less than -0.31. Thus, the answer is choice B. Using a standard normal distribution table or calculator, we find that the probability of getting a z-score less than -0.31 is 0.3783.
