- Imagine a weight swinging back and forth on the end of a string. In a perfect situation, the weight would swing back and forth forever without stopping. If were the case, how could you model the distance of the weight from the center over time? What would a graph of that model look like? What type of function could you use to create this model? What are some other types of situations you could model similarly?

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?
