It is essential to show all steps by hand!! Also if a method is prescribed use only that method! 8)justifying its use, use L'Hospital's Rule to evaluate the following limit: lim ln(x^8) / 8x^8-8 x->1
Find the upper and lower control limits for /x- and R-charts for the width of a chair seat when the sample grand mean (based on 30 samples of 6 observations each) is 27.0 inches, and the average range is 0.35 inches.
Use one-sided limits to find the limit or determine that the limit does not exist: limx => 4 16-x^2 / 24-x The problem might be easier to read like this: limit 16 - x^2 x --> 4 24 - x
