The strength of one's immune system can be evaluated in several ways. one of the most popular methods involves measuring the concentration of adenosine triphosphate (atp) in the blood. in women, the mean blood atp level is 390 ng/ml, and the standard deviation is 115 ng/ml. it has been hypothesized that women with major depressive disorder (mdd) have decreased immune function. a recent study found that a random sample of 88 women with mdd had an average blood atp level of 355 ng/ml. using a one-sample z test, what is the p-value of this result? (hint: this involves a one-tailed hypothesis test.)

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3
