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

answer

the correct answer is

explanation

the given function is

the excluded values are obtained by solving:

we factor to obtain:

the excluded values are

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
