Quizplus · Accepted Answer

The probability that a standard normal variable z lies between -0.55 and 0.55 is found using the standard normal distribution table. The probability for z < 0.55 is approximately 0.7088, and for z < -0.55 is approximately 0.2912. The difference, 0.7088 - 0.2912, gives the probability of z being between -0.55 and 0.55, which is 0.4176.
