Quizplus · Accepted Answer

The standardized normal distribution table or a calculator can be used to find P(z > 1.645). This value corresponds to the area to the right of z = 1.645 under the standard normal curve, which is 0.05. This is commonly used in statistics for one-tailed tests at the 5% significance level.
