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.
1000 gram = 1 kilogram
If 200 gram = $8.12. 1, it means we can get 5 bags of such amount (1000/200 = 5)
Therefore, 1kg = $8.12 * 5 = $40.6
