A facility for bottling soda uses two fill and seal machines. As part of quality control, data are periodically collected from random samples to test if the fill weight is the same for the two machines. A particular sample of 12 observations per machine were collected with the following summary statistics: (a) Conduct a hypothesis test to see if there is a difference in the mean fill amount of the machines Complete a hypothesis test. (b) Construct a 95% CI on the difference of means of the two soda bottling machines. Interpret. (c) Based on the results of the hypothesis test, what kind of error could have been made (in context)? 2 Machine n 966.75 12 29.3 962.33 12 26.24

    A facility for bottling soft drinks uses two fill and seal machines. For quality control purposes, data is collected on these machines to determine if they are filling the soft drinks with the same amount of drink. Based on data from these two machines, they found that a 95% confidence interval for the difference in these machines, population means is (-2.5 mL, 0.3 mL). Using this data, the bottling facility would like to test if there is a difference in...

    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...

    3. Two machines are used for filling plastic bottles with a net volume of 16.0 ounces. The fill volumes on both machines can be assumed to be normally distributed. The quality engineering department suspects that both machines fill to the same net volume, whether or not this volume is 16.0 ounces.

    The melting points of two alloys used in formulating solder were investigated by melting 21 samples of each material. The sample mean and standard deviation for alloy 1 was 420.48 and 2.34 respectively, and for alloy 2 they were 425 and 2.5 respectively. Do the sample data support the claim that both alloys have the same melting point? Use a fixed-level test with alpha=0.05 and assume that both populations are normally distributed and have the same standard deviation. Provide the...
