Answer:
Here are some possibilities:
a.) 9 + -9 = 0
b.) 8 + 2 + -10 = 0
c.) 6 + 4 + -2 + -8 =0
Given:Sample mean= 57
Standard Deviation= 9
score of 59
we go to our standard formula:
(score - mean) / sd = z
(59 - 57) / 9 = z
2/9 = z
0.2222 = z
Failing score cutoff would be equal to Mean - 2SD = 67 - 2(9) = 48 is failing score cutoff.
