The old machine filled 12 soda cans with an average of 11.9 oz of soda with a standard deviation of 0.3 ounces.

The old machine filled 12 soda cans with an average of 11.9 oz of soda with a standard deviation of 0.3 ounces. The new machine still fills them (11 cans) with an average of 12.1 ounces, with a standard deviation of 0.3 oz. Is the new machine filling with significantly more than the old machine? (α=.05)

The management of a soda company wanted to determine the average number of ounces of soda...

The management of a soda company wanted to determine the average number of ounces of soda consumed per resident in the state of Pennsylvania. Past trends indicate that the variation in soda consumption (σ) was 4 ounces. A 95% confidence level is required, and the error is not to exceed +/- 1/2 ounce. (a) What sample size would you recommend? Show your calculations. (b) The management wanted an estimate twice as precise as the initial precision level and an increase...

Most soda cans list the volume of soda as 12 fluid ounces. As with all process, some variation occurs when filling soda cans. Suppose that a company knows this and tries to over-fill cans a bit, so that the actual volume of soda in a can follows a normal distribution with mean 12.1 fluid ounces and standard deviation .15 fluid ounces. a) What proportion of soda cans filled by this process will contain less than 12 fluid ounces? (In other...

It is assumed that there is an average of 12 customers per hour at a service counter according to a Poisson process. a) How likely is it that 4 customers show up at this counter in the next 15 minutes? b) Given that 4 customers showed up at this counter in a given 15-minute period, what is the probability that there were at least 2 customers that showed up in the last 5 minutes of this period?

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...

An average of 12 ounces of beer is used to fill each bottle in a local brewery as recorded. The manager now believes that, in general, beer bottles are overfilled. He takes a random sample of 30 bottles to test. The sample mean weight of the bottles is 12.8 ounces with a standard deviation of 1.5 ounces. Conduct a one-sample t-test to test whether the beer bottles are overfilled. Use 5% level of significance. (Round your steps to 4 decimal...
