chipmunks in a particular chipmunk population are known to have a mean weight of 84 g and a standard deviation of 18 g. Mr. Weaver weighs 9 chipmunks that have been caught in live traps before releasing them. Which of the following best describes what we know about the sampling distribution of means for his sample? Assume the 9 chipmunks represent a simple random sample of chipmunks in the area. a. x = 84, x = 18, distribution approximately Normal b. x = 84, x = 6, shape of distribution unknown
