0.06 times 96 equals 5.76
Mean, x_bar = 1518
Standard deviation, sigma = 325
Range required: 1550 ≤ X ≤ 1575
Z = (X - x_bar)/sigma
Z1 = (1550-1518)/325 ≈ 0.1
Z2 = (1575-1518)/325 ≈ 0.18
From Z tables,
P(Z1) = 0.5398
P(Z2) = 0.5714
P(1550≤X≤1575) = P(Z2) - P(Z1) = 0.5714 - 0.5398 = 0.0316
The correct answer is C.

If there are fraction, just turn them into decimal
- 1/3 = -0.3333....... 1/3 = 0.3333........
when ordering them just think of a number line, because a number line start from negative to positive, then just put the negative numbers first if it asks you to "order from least to greatest" if it asks "order from greatest or least" then put positive numbers first
-0.5 < 1/3 < 1/3 < 0.5 < 1.25
