The Sampling Distribution of Y̅

Example: Sampling DistributionIn a certain population of fish, the lengths of
individual fish follow a normal distribution with mean 54 mm and standard deviation 4.5 mm
a) What is the probability that a random chosen fish is between 51 and 60 mm long?
b) Suppose we sample 4 fish, what is the probability that the mean length of the four fish is between 51 and 60 mm long?

Example 5.2.3: Sampling Distribution/Population Size
This shows the sampling distribution for the samples of various sizes from a princess bean population (Example 5.2.2). Here the population mean is μ = 500 mg.
