21 25 21 19 16 18 19 19 16 24 21 21 17 26 20 23 20 21 20

For a one-tailed test or directional hypothesis, the researcher is interested in results that occur in only one tail of the normal curve (e.g., they are interested in extreme high scores or extreme low scores). Therefore, when using the 5% criteria to judge the likelihood of a score, the researcher identifies the score that divides the curve into two parts (one part containing 95% of the scores and the other part containing 5% of the scores). What value of z separates the normal curve into these two sections? (You may need to refer to Table B.1).
