6. 7-Up Example: A can of 7-Up states that the can contains 355 ml. A quality control engineer is worried that the filling machine is mis calibrated. In other words, she wants to make sure the machine is not under- or over-filling the cans. She randomly selects 9 cans of 7-Up and measures the contents. She obtains the following data. 351 360 358 356 359 358 355 361 352 Is there evidence at the α=0.05 level, to support the quality control engineer’s claim? Check Assumptions: Ho: Diagram: H1: Statistical Variables: Test Statistic: P-Value: Conclusion and Interpretation: 7. CONFIDENCE INTERVAL Compute the 95% confidence Interval for the mean contents of the 7-up cans using the data above. Use your result to test the quality control engineer’s claim that the filling machine is miscalibrated.

Can you do 6 and 7. I'll give thumbs up 6. In a recent year, the SF Giants won 47 of 81 home games and they won 37 of 81 away games. Use a 0.05 significance level to test the claim that the proportion of wins for home games is greater than the proportion of wins for away games. Does there appear to be a home-field advantage? 7.In a recent year, the San Diego Padres won 45 of 81 home...

ABC Drinks purchases its 355 ml cans in large bulk from Wald-China Can Corporation. The finish on the anodized aluminum surface is produced by mechanical finishing technology called brushing or bead blasting. Engineers at Wald are switching to more efficient, faster, and cheaper machines to supply ABC. Use the estimates and MARR=8% per year to select between two alternatives. Brush alternative: P=$-400,000; n=10 years; S=$50,000; nonlabor AOC=$-60,000 in year 1, decreasing by $5000 annually starting in year 2. Bead blasting...

A bottle of soft drink states that it contains 500 ml. A consumer group is angry and claims that the bottles are actually under-filled. The group takes a random sample of 40 bottles and finds a mean of 492 ml, with a sample standard deviation of 10 ml. Is their claim valid using the 0.01 level of significance? Use the five-step procedure to answer the question and include the p-value.

A manufacturing lot contains 40 items. It is known that 6 items are defective. A quality assurance engineer selects a random sample of 10 items and checks each to see if it is defective. i. What is the mean and standard deviation of the number of defective items that she will sample. [4] ii. What is the probability that she observes two or fewer defective items. A road surface is being inspected for potholes. The number of potholes per kilometre...

An urn contains 4 white balls and 6 red balls. A second urn contains 7 white balls and 3 red balls. An urn is selected, and the probability of selecting the first urn is 0.1. A ball is drawn from the selected urn and replaced. Then another ball is drawn and replaced from the same urn. If both balls are white, what are the following probabilities? (Round your answers to three decimal places.) - (a) the probability that the urn...

DAB Standard 6 contains requirements for the physical set-up of the laboratory facility. Access to the laboratory is controlled and limited Evidence examination, DNA extraction, and PCR set-up are conducted in separate places or at separate times. Amplified DNA is confined to rooms separate from those used for other steps. Robotic workstations used to carry out DNA extraction, quantification, PCR setup, and/or amplification in a single room must be in a separate room from initial evidence examinations. Written procedures for...
