Homework Help: According to the article "Are Babies Normal?" by Traci Clemons and Marcello Pagano published in The American Stat
istician, Vol. 53, No. 4, pp. 298-302, the birth weights of babies are normally distributed with a mean of 3320 grams and a standard deviation of 564 grams. 1. What is the probability that the average weight of 13 randomly selected babies is between 3000 grams and 3600 grams? Round your answer to 4 decimal places.
So, since 100% = 128, x should equal 96, and we are trying to find x. Multiply both sides of the equation by x. (100/x) * x = (128/96) * x Cancel out the x's on the left side so 100 = 1.333(x) 75 = x 96 is 75% of 128
