Question 1204602: A manufacturer knows that their items have a lengths that are skewed right, with a mean of 13.5 inches, and standard deviation of 3.4 inches.
If 46 items are chosen at random, what is the probability that their mean length is greater than 12.3 inches?

x̄ = => mean length
sample size
population mean
standard deviation
to find: (x̄ > )
z-statistic: (x̄ -)/
compute z-statistic for x̄ =
=>% chance of the sample mean being greater than inches long
