Use Garbage.xls file which consists of data from 60 fictional homes on Concordia St.  It includes variables regarding the household size, the pounds of each type of garbage disposed in a week, the total weight of their garbage each week, and whether or not the household recycles.

  • ASSIGNED PROBLEM 1:  First compute the mean total weight and standard deviation of the garbage disposed each week by the sample; use the Descriptive_Statistics.xls file if needed.  Then compute the 95% confidence interval of the mean total garbage disposed of in a week on Concordia St.  Describe your findings.
  • ASSIGNED PROBLEM 2:  First compute the proportion of homes in the sample that recycle.  Then compute the 95% confidence interval of the proportion of homes on Concordia St. that recycle.    Describe your findings.
  • ASSIGNED PROBLEM 3:  You wish to learn the average number of pounds of garbage disposed of in a week by the people on Concordia St. within 2 pounds.  Using the standard deviation from problem 1as an estimate, how large of a sample should you get? 
  • ASSIGNED PROBLEM 4:  You wish to learn the proportion of homes on Concordia St. that recycle within 10% and with 99% confidence.  How large of a sample should you get?
