    The image below is labeled with A, B, C, and D, which correspond to columns in the table.

    • A refers to the \(z\) score.
    • B refers to the body, the larger area on one side of a \(z\)-score.
    • C refers to the tail, the smaller area on one side of a \(z\)-score.
    • D refers to the area between the mean and the \(z\)-score.

    This table provides only positive \(z\)-scores, as the standard normal distribution is symmetric.

    Three bell curves showing normal distributions; the first two have shaded left and right tails labeled alpha, the third has a central shaded area labeled 1-alpha between z-scores.
