Question: Given a population of light bulbs has a mean lifespan of 1000 hours and a standard deviation of 56 hours. (This not a trick question. It is also not a hard question to answer.)
-
What is the mean and standard deviation of the sampling distribution when we take all samples of size 25?
MEAN =
STANDARD DEVIATION = - If we take larger size samples which of the values (for the mean and standard deviation found in part a) above will change and will it go up or down?
