Would you be more likely to buy coffee from a coffee shop or a vending machine if you were in a hurry?
Q : Let's say you are in an airport and your plane is now boarding, you are a regular coffee drinker and you really want coffee.Or let's say you are a college student studying for exams in the library and you wanted coffee.
A : If I drink coffee, I want coffee, not that excuse of a substance that comes out of a machine
What effect on taste do different waters types have on brewed coffee, we usually use vending machine?
Q : water for our coffee, we also buy water bottle, and tap water would be out of the question. Also, what is the best water to use, thanks
A : For taste use filtered water because water with a bad or off taste will make bad coffee. Afterall, coffee is mostly water.
For your equipment, use filtered water as mineral buildup will damage coffee machines.
Is there individual packing of the vending machine coffee drinks?
Q : I really like the vending machine coffee and was just wondering if anyone knows if certain companies sell individual packages of the coffee
A : I better guess not. I may be wrong also????
A coffee vending machine is regulated weekly so that the amount of coffee poured out from the valve is 8.0 oz.?
Q : The distribution is normal with standard deviation, SD = 0.4 ounces. Suppose the cup can only holds up to 8.5 ounces.
(a) Find the probability of spilling
(b) A regular customer complains about the spilling problem whenever it occurs. He buys 1 cup of coffee every day. What is the probability of complaining more than 2 times in a week (7 days)?
(c) 400 cups were sold in a day. Find the probability that there are more than 40 spilling.
A : Average = 8.0 oz.
Stadard deviation= o.4
Standard normal variable for 8.5 oz= (8.5-8.0)/0.4 =1.25
Area of normal distribution curve from z = 0 to z =+1.25 is 0.8944
Hence area to the right of z = 1.25 = 1- 0.8944 = 0.1056
Hence there is 10.56 % probability that the coffe poured out is in excess of 8.5 oz. in other words there is spilling.
