A bottle filling machine fills, on average, 20,000 bottles a day with a standard deviation of 2,000. If we assume that the production is normally distributed and that a year comprises 260 working days. Answer the following questions. (A normal curve may be helpful)
What is the approximate number of working days that more than 32,000 bottles are filled?
Homework Answers
Given that, mean (μ) = 20000 bottles and
standard deviation 
= 2000 bottles
Number of working days = 260
First we find, P(X > 32000)
Therefore, the approximate number of working days that more than 32000 bottles are filled is, 260 * 0 = 0
Answer : 0 days

A machine fills milk bottles. The amount of milk poured by the machine in each bottle is approximately normal with unknown mean u and standard deviation o = 0.06 oz. To meet company operational standards, the machine should pour with mean = 32 oz.

A machine fills bottles with 48 fluid ounces of liquid. The quality-control manager determines that the fill levels are normally distributed with a mean of 48 ounces and a standard deviation of 0.38 ounces. He has an engineer recalibrate the machine in an attempt to lower the standard deviation. After the recalibration, the quality control manager randomly selects 19 bottles from the line and determines that the standard deviation is 0.34 ounces. Using a level of...

A machine at Ken's Ketchup Corporation fills 20-ounce ketchup bottles. The machine can be adjusted to pour, on average, any amount of ketchup into these bottles. However, the machine does not pour exactly the same amount of ketchup into each bottle. It varies from bottle to bottle. It is known that the net amount of ketchup poured into each jug has a normal distribution with a standard deviation of 0.25 ounce. The quality control inspector wants to adjust the machine...
