The owner of a local supermarket wants to estimate the difference between the average number of gallons of milk sold per day on weekdays and weekends. The owner samples 24 weekdays and finds an average of 242.462 gallons of milk sold on those days with a standard deviation of 36.143. 28 Saturdays and Sundays are sampled and the average number of gallons sold is 335.717 with a standard deviation of 43.83. If a 95% confidence interval is calculated to estimate...

The supermarket GoodFood orders fresh milk daily directly from Farmer Brigg. The daily demand for milk at the supermarket is normally distributed with an expected demand of 100 gallons and a standard deviation of 20 gallons. GoodFood pays $0.70 per gallon and sells the gallon for $1.00. If GoodFood has milk left over at the end of the day, he cannot keep it and sell it the next day, because it will be sour. However, Farmer Brigg can feed the...

Suppose that a grocery store buys milk for $2.10 and sells it for $2.60. If the milk gets old then the grocery store can sell their unsold milk back to their wholesaler for $0.60 (so the grocery store loses $1.50 on each gallon that it has to sell back to the wholesaler). Suppose that the demand for milk is normally distributed with a mean of 2,384 gallons per week and a standard deviation of 431 gallons per week. The grocery...
