Suppose babies born in a large hospital have a mean weight of 4090 grams, and a variance of 313,600. If 64 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would differ from the population mean by greater than 43 grams

Step-by-step explanation:

mean weight of baby = 4090 gms

standard deviation = √ 313600

= 560

z value = deviation / standard deviation

= 43 / 560

= .0767

452,489 to the nearest thousand is 452,000

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
