Suppose delivery time for distributors in an area are normally distributed and have a known population standard deviation of 9 minutes and an unknown population mean. A random sample of 21 distributors is taken and gives a sample mean of 161 minutes. Find the error bound (EBM) of the confidence interval with a 90% confidence level.

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
