Question 1204738: A laser printer is advertised to print text documents at a speed of 18 ppm (pages per minute). The manufacturer tells you that the printing speed is actually a Normal random variable with a mean of 17.25 ppm and a standard deviation of 4 ppm.
1) suppose that we draw a random sample of 32 printers. find the probability that the mean of our sample will be greater than 18.05 ppm.
2) suppose that we found all possible sample means for a sample of size32. Find the values that approximately 95% of the sample means would fall between. Answer by mananth(16946) (Show Source):
