As part of a study for a new medication, a drug company samples cholesterol levels from a group of patients. the company reports that a 90% confidence interval for the cholesterol levels for the population being studied is (127.6, 168.8). what is the margin of error? a) 18.54 b) 20.60 c) 37.08 d) 41.20

Answer-

The margin of error of the sample is 20.60

Solution-

We know that,

where:

According to the question,

Subtraction equation 2 from equation 1,

Therefore, the margin of error of the sample is 20.60

step-by-step explanation:

its a wood chuck that can chuck wood

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
