Answer:
Z score = (reading - 45)/ 16
so Z score for 38.60 >>>> Z = (38.60 - 45)/16 = -0.4923
Z score for 57.80>>>>>>>Z = (57.80 - 45)/16 = 12.80/16 = + 0.8
Now consult a Table of Z values to get the answers.
All values in the table are positive. Your first Z score is negative but the negative sign only tells you that your reading is less than the average.
