18. A laboratory tested a simple random sample of twelve chicken eggs and found that the data fit a nomal distribution and that mean amount of cholesterol was 225 milligrams with ans = 15.7 milligrams. Find the margin of error and confidence interval that corresponds to the given statistics and a confidence level of 95%. A E= 10.0354, CI = (212.0226, 237.9236) C) E= 6.2246, CI = (218.3254, 238.6984) B) E = 2.2546, CI = (216.0652, 233.9652) D) E= 9.9753, CI = (215.0247,234.9753)​

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
