A student asked 100 coffee drinkers if they like cream or sugar in their coffee. Out of those surveyed, 36 like cream in their coffee, 55 like sugar in their coffee, and 29 like neither cream nor sugar.
Draw a Venn diagram and appropriately indicate “Cream,” “Sugar,” “Cream and Sugar,” and “neither Cream nor Sugar”. Include the correct numerical values in each section.
How many of the coffee drinkers like cream and sugar?
How many coffee drinkers like cream or sugar?
How many coffee drinkers like cream but not sugar?
How many coffee drinkers like sugar but not cream? ]
If the student was to ask another sample of 350 coffee drinkers, how many would she expect to like cream and sugar in their coffee?

A female just had a cup of coffee with cream and sugar. You are
following the journey of the glucose molecule from ingestion thru
cellular respiration which creates H2O and CO2. You will follow the
CO2 molecule until exhalation and the H2O to excretion. List the
following pathways.
A.
List
the physical pathway from the oral cavity to the point of
absorption in the gastrointestinal tract.

A coffee manufacturer is interested in whether the mean daily
consumption of regular- coffee drinkers is less than that of
decaffeinated coffee drinkers. Assume the population standard
deviation for those drinking regular coffee is 1.21 cups per day
and 1.40 for those drinking decaffeinated coffee. A random sample
of 54 regular coffee drinkers showed a mean of 4.59 cups per day. A
sample of 49 decaffeinated coffee drinkers showed a mean of 5.64
cups per day.
