Solution-What proportion of coffee drinkers have or

What proportion of coffee drinkers have or morecups per day

Reference no: EM132174781

Question 1:

Among coffee drinkers, men drink on average 2 cups per day (mean=2) with a standard deviation sd= 0.5 cups. Assume the X= number of cups per day, X follows a normal distribution, and thus Z = (X- mean)/SD

You must show your work.

a. What proportion of coffee drinkers have3 or morecups per day?

b. What proportion of coffee drinkers haveno more than 3 cups per day?

c. If the top 10% of coffee drinkers are considered "heavy" coffee drinkers, what is X the minimum number of cups consumed by a heavy coffee drinker?

d. If the 25th percentile separates the "light" coffee drinkers from the rest, what is X the maximum number of cups consumed by the light coffee drinkers?

REMEMBER to define the missing values, label your categories when dealing with nominal/ordinal variables, and recode your variables (ex, into binary ones) when required by the analysis. Please don’t change the numbering of the questions. I intentionally provided the exercises to you on separate pages so that the question and sub question numbering is less likely to be changed when you copy and paste tables from SPSS or when you write in your answers. Please make sure the tables are not scrambled. Try to paste the table as image, or simply use the “export” feature of the SPSS Output? export the table as a word document and then copy it from that document.
