Answer 1

Answer #1

The margin of error(ME) at 5% for the current machine is 07.025 = 1.959964/16 = 0.1224978

The margin of error(ME) at 5% for the new machine is OT.025 <= 1.959964/32 = 0.06124888

Thus the margin of error at 95% for the new machine is at most 0.06124888", which is almost half of that for the current machine.

Hence we say with 95% confidence that the new machine will be an improvement in terms of precision.

For any query in above, comment.

Company XYZ know that replacement times for the quartz time pieces it produces are normally distributed with a mean of 15.4 years and a standard deviation of 1.4 years. Find the probability that a randomly selected quartz time piece will have a replacement time less than 12.6 years? P(X < 12.6 years) If the company wants to provide a warranty so that only 3.2% of the quartz time pieces will be replaced before the warranty expires, what is the time...

Lazarus Steel Corporation produces iron rods that are supposed to be 36 inches long. The machine that makes these rods does not produce each rod exactly 36 inches long. The lengths of the rods are normally distributed, and they vary slightly. It is known that when the machine is working properly, the mean length of the rods is 36 inches. The standard deviation of the lengths of all rods produced on this machine is always equal to .035 inch. The...
