Quizplus · Accepted Answer

The probability p(z > +1.78) refers to the area under the standard normal distribution curve to the right of z = +1.78. This is found by looking up the z-score in a standard normal distribution table or using a calculator designed for statistical functions. The value .0375 corresponds to the area to the right of z = +1.78, indicating that there is a 3.75% chance that a randomly selected score from a normal distribution will be greater than +1.78 standard deviations above the mean.
