The confidence interval of 23 to 30 is determined using a sample mean of 26.5.
What is the margin of error?

A) 5
B) 3.5%
C) 3.5
D) 5%

your mom.

That reminds me:  A poll said that 75% of people prefer regular butter to butter substitutes, correct to within plus or minus 4% margarine of error, 19 times out of 20.

ok, (30-23)/2 = 3.5, or if you want percent relative to mean, 3.5/26.5*100% = 13.2%
