Traditionally, wine has been sold in glass bottles with cork stoppers. The stoppers are supposed to keep air out of the bottle because oxygen is the enemy of the wine. Particularly red wine. Recent research appears to indicate that metal screw caps are more effective in keeping air out of the bottle. However, metal caps are perceived to be inferior and usually associated with cheaper brands of wine. A random sample of 130 people who drink at least one bottle per week on average was asked to participate in an experiment. All were given the same wine in two types of bottles. One group was given a corked bottle, and the other group of people was given a bottle with a metal cap and asked to taste the wine and indicate what they think the retail price of the wine should be.

METAL PRICE = 13 12 16 5 7 8 6 10 11 9 6 16 15 15 9 17 6 10 11 7 8 11 22 21 11 6 11 10 17 12 13 11 16 18 12 11 11

CORK PRICE = 16 10 15 10 17 11 14 13 11 14 11 16 18 16 10 17 14 14 16 7 10 12 19 15 16 14 9 12 21 13 10 16 12 16 13 17 17

Wine bottles are never completely filled: a small volume of air is left in the glass bottle's cylindrically shaped neck (inner diameter dd = 18.5 mmmm) to allow for wine's fairly large coefficient of thermal expansion. The distance H between the surface of the liquid contents and the bottom of the cork is called the "headspace height"(Figure 1), and is typically H = 1.5 cmcm for a 750-mLmL bottle filled at 20 ∘C∘C. Due to its alcoholic content, wine's coefficient...

Southern Glass manufactures glass bottles for a variety of products, including perfume bottles and liquor bottles. The company has two profit centers: production and labeling. The production department melts the raw materials, adding metal oxides to produce different colors if desired. It then uses a continuous rolling process to shape the bottles. Production then transfers the bottles to the labeling department at an average cost of $15 ($12 variable; $3 fixed) per case. The labeling department then paints or attaches...

A local winery bottles thousands of bottles of wine per season. The winery has a machine that automatically dispenses the amount of wine per bottle before aging. Each season the wine maker randomly samples 45 bottles of wine to ensure the amount of wine per bottle is 750 ml. If there is evidence that the amount is different than (less or more than) 750 ml then the winery will need to evaluate the machine and perhaps rebottle or consider selling...
