The manager of a printing shop checks a chart that shows the thickness of different weights of paper in microns (thousandths of a millimeter) to ensure he uses the right settings on the printing machines. The pieces of paper are all between 100 and 200 microns thick, with most less than 160 microns. The mean thickness is about 136 microns, and the mean absolute deviation is about 23 microns.Which is a typical thickness of a piece of paper?Choices:(A) 23 microns(B) 136 microns(C) 160 microns(D) 200 microns
Q. The manager of a printing shop checks a chart that shows the thickness of different weights of paper in microns (thousandths of a millimeter) to ensure he uses the right settings on the printing machines. The pieces of paper are all between 100 and 200 microns thick, with most less than 160 microns. The mean thickness is about 136 microns, and the mean absolute deviation is about 23 microns.Which is a typical thickness of a piece of paper?Choices:(A) 23 microns(B) 136 microns(C) 160 microns(D) 200 microns
Identify Mean Thickness: Identify the mean thickness from the given data; the mean represents the typical value in a set of data. Calculation: Mean thickness =136 microns.
Compare Mean to Choices: Compare the mean thickness to the provided choices. Choices are: (A) 23 microns, (B) 136 microns, (C) 160 microns, (D) 200 microns. Since the mean thickness is 136 microns, choice (B) matches the mean.
Verify Mean Thickness Range: Verify if the mean thickness falls within the range of typical paper thicknesses mentioned (100 to 200 microns, mostly less than 160 microns). Calculation: 100 microns ≤136 microns ≤160 microns.
