Question

in a normal distribution of z scores, the most common z score value is: -3 -1 3 0 1 question 12 0.66 pts if the area of the normal curve you want to find is more than half of the distribution, you should use the ____________ column of the unit normal table to find its area. body tail

Explanation:

1. In a normal distribution of z - scores, the mean of the standard normal distribution is 0, and the peak of the normal curve occurs at the mean, so 0 is the most common z - score value.
2. The unit normal table has two main parts: the body and the tail. The body of the unit normal table gives the area between the mean (z = 0) and a positive z - score. If the area of the normal curve we want to find is more than half of the distribution, we use the body column as it represents larger areas starting from the mean.
