• Important information about Introduction to Hypothesis Testing

  (b) As s (or ) increases, SE increases resulting in a decrease in the z- score. The z- score goes closer to 0. As s (or ) decreases, SE decreases resulting in an increase in the z- score. The z- score goes farther from 0.

• Normal z score for normally distributed data

  a. z=(22-20)/5=0.4 b. z=(22-30)/5=-1.6 c. z=(22-16)/2=3 d. z=(22-10)/8=1.5 so student c had the highest score value because its z score is highest student b did the poorest in this group because its z score is lowest The solution gives

• Probability

  Here it is given that X=65 corresponds to a z-score of Z= 2.00, and a score of X= 44 corresponds to a z-score of Z = -1.50. Thus (65-m)/s = 2 and (44-m)/s = -1.5 i.e., m + 2 s = 65 and m ?
