In a study of the effect of diet on cholesterol, rats were fed several different diets. one diet had 5% added fiber from oat bran. the study report gives results in the form "mean plus or minus the standard error of the mean." this form is very common in scientific publications. for the 9 rats fed this diet, blood cholesterol levels (in milligrams per deciliter of blood) were 89.02 ± 5.26. what are x and s for these 9 rats? (use 2 decimal places.)

x = 89.02 milligrams

s = 15.78 milligrams

Step-by-step explanation:

Data provided:

Mean plus or minus the standard error of the mean = 89.02 ± 5.26

Sample size, n = 9 rats

Now,

x is the mean of the sample of 9 rats i.e 89.02 milligrams (as given in the question)

and,

s is the standard deviation

The standard deviation can be calculated using the relation:

Standard error =

on substituting the respective values, we get

5.26 =  

or

Standard deviation = 5.26 × 3

or

Standard deviation = 15.78 milligrams

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
