A manufacturer fills soda bottles. Periodically they test to see if there is a difference in the amount of soda put in cola and diet cola bottles. A random sample of 14 cola bottles contains an average of 502 mL of cola with a standard deviation of 4 mL. A random sample of 16 diet cola bottles contains an average of 499 mL of cola with a standard deviation of 5 mL. Test the claim that there is a difference in the fill levels of the two types of soda using a 0.01 level of significance. Assume that the population variances are different since different machines are used for the filling process.

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...

D Question 11 3 pts A manufacturer of perfume produces bottles that are supposed to contain an average of 120 ml of perfume. The standard deviation of the filling process is known to be 12 ml, and the distribution of the amount of perfume in the bottles is known to be approximately normally distributed. In order to test its filling process, the quality control inspector selects a random sample of 45 bottles. He measures the amount of perfume in each...

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...
Is there enough evidence to say that the machine is not filling the bottles with an average of 16 ounces at the 5% significance level?
A bottling machine at a cola plant is being tested to ensure that it is filling the bottles with average of exactly 16 ounces of soda. A SRS of 40 bottles are tested which had a sample mean content of 15.95 ounces and a sample standard deviation of .18 ounces.Please show the four steps of your analysis in the space provided below...

A bottling company uses a filling machine to fill plastic bottles with a popular cola. The bottles are supposed to contain 300 milliliters (ml). In fact, the contents vary according to a normal distribution with mean µ=303 ml and standard deviation σ= 5 ml What is the probability that an individual bottle contains greater than 305 ml? What is the probability that the sample mean of 100 bottles is less than 302 ml?

A golf balls manufacturer requires that the weights of its golf balls have a standard deviation that is less or equal 0.08 ounces. One of the quality control inspectors says that the machines need to be recalibrated because he believes (claims) the standard deviation of the weighs of the golf balls is more than 0.08 ounces. To test the machines, he selects a random sample of 50 golf balls off the assembly line and finds that they have a mean...
