Step-by-step explanation:
y-intercept (0,2.5)
x-intercept (3.5,0)
The z-score is the number of standard deviations from the mean. For a given x-value, mean (μ), and standard deviation (σ) the z-score is given by
... z = (x -μ)/σ
(a) x=196, μ = 180, σ = 8 gives a z-score of
... z = (196 -180)/8 = 16/8
... z = 2.0
(b) The area associated with x=2 is 0.4772
(c) Rounded to the nearest thousandth, this is 0.477
(d) Carl's subtraction gives
... 0.50 - 0.477 = 2.3%
1 pint = 0.473176 liter
so 50 pints x 0.473176 = 23.6588 liters
