1.For the two-tailed or non directional hypothesis, the researcher is interested in results that occur in either tail of the normal curve (extreme high and extreme low scores).Therefore, when using the 5% to judge the likelihood of a score, the researcher identifies the score that divides the curve into three parts (first the lower 2.5% scores, second containing the middle 95%, third containing the upper 2.5% scores).What value of z separates the normal curve into these three sections?
