Suppose across all colleges, the variable Current Visits to Coffee Shop is approximately normally distributed with a mean of two visits per week, with a standard deviation of 0.73 visit per week.
If we were to randomly sample 25 students, what is the probability that the mean number of visits is:
Less than 1.8
Between 2 and 2.08
More than 2.15
Less than 1.8 or more than 3
Take a simple random sample 25 people from Colorado Community College (use the Coffee Shop Survey dataset).
Explain how you conducted the random sample.
Calculate and give the mean.
What conclusion can you reach about Colorado Community College students compared to all college students. Explain.
Your boss has asked you to format this as an email where you give
both the answers and the Excel Syntax you needed for calculations, in
case they want to recreate the work on their own.
Submit what you would send your boss as a PDF to the dropbox.
