A ferritin test is a popular test to measure a person’s current iron stores. in women, ferritin is normally distributed with a m
MArishka [77]
Given:
μ = 89 ng/ml, population mean
σ = 23 ng/ml, population standard deviation

Random variable, x = 100
To test P(x < 100), calculate the z-score.
 z = (x-μ)/σ = (100 - 89)/23 = 0.4783

From standard tables, obtain
P(x < 100) = 0.6838 = 68.4%

Answer: 68.4%

What is the equation of the line, in point-slope form, that passes through the points (-1, 7) and (-2, 3)? A. y + 7 = -4(x - 1)
Nana76 [90]

In general point-point form, the equation for the line through (a,b) and (c,d) is

(c-a)(y-b) = (d-b)(x-a)

Here we have (a,b)=(-1,7) and (c,d)=(-2,3)

(-2 - -1) (y - 7) = (3 - 7)(x - -1)

-1(y - 7) = -4(x+1)

y - 7 = 4 (x+1)

Answer: Choice D
