0.01 rejecting the null hypoth 3. (20 pts) A machine fills bottles with 64 fluid ounces of liquid. The quality control manager determines that the fill levels are normally distributed with a mean of 64 ounces and a standard deviation of 0.42 ounce. He has an engineer recalibrate the machine in an attempt to lower the standard deviation. After the recalibration, he randomly selects 19 bottles from the line and determines that the standard deviation is 0.38 ounce. Use the....

A quality-control engineer wants to find out whether or not a new machine that fills bottles with liquid has less variability than the machine currently in use. The engineer calibrates each machine to fill bottles with 16 ounces of a liquid. After running each machine for 5 hours, she randomly selects 15 filled bottles from each machine and measures the volume of their contents (in ounces). The resulting data is provided in the table below. Is the variability in the...

Suppose a brewery has a filling machine that fills 12 ounce bottles of beer. It is known that the amount of beer poured by this filling machine follows a normal distribution with a mean of 12.19 ounces and a standard deviation of 0.04 ounce. Find the probability that the bottle contains between 12.09 and 12.15 ounces.
Suppose a brewery has a filling machine that fills 12 ounce bottles of beer
Suppose a brewery has a filling machine that fills 12 ounce bottles of beer. It is known that the amount of beer poured by this filling machine follows a normal distribution with a mean of 12.41 ounces and a standard deviation of 0.04 ounce. Find the probability that a randomly selected bottle contains between 12.31 and 12.37 ounces.

Suppose a brewery has a filling machine that fills 12 ounce bottles of beer. It is known that the amount of beer poured by this filling machine follows a normal distribution with a mean of 12.16 ounces and a standard deviation of 0.04 ounce.

A soda bottling plant fills cans labeled to contain 12 ounces of
soda. The filling machine varies and does not fill each can with
exactly 12 ounces. To determine if the filling machine needs
adjustment, each day the quality control manager measures the
amount of soda per can for a random sample of 50 cans. Experience
shows that its filling machines have a known population standard
deviation of 0.35 ounces.
In today's sample of 50 cans of soda, the sample...

Suppose a brewery has a filling machine that fills 12 ounce bottles
of beer. It is known that the amount of beer poured by this filling
machine follows a normal distribution with a mean of 12.36 ounces
and a standard deviation of 0.04 ounce. Find the probability that
the bottle contains between 12.26 and 12.32 ounces.

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...
