Cholesterol is a fatty substance that is an important part of the outer lining (membrane) of cells in the body of animals. Suppose that the mean and standard deviation for a population of individuals are 180 mg/dl and 20 mg/dl, respectively. Samples are obtained from 25 individuals, and these are considered to be independent. What is the probability that the average of the 25 measurements exceeds 185 mg/dl?

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
