The entire lab, including first part (lab 11) is due Monday at class time  Nov 13

*1.      What are the expected probabilities associated with you 20 sample means according to the
          central limit theorem?

*2..    Please calculate a 95% confidence interval  for the 20 sample means randomly sampled in the last lab exercise.

   3.     A.    How many of the intervals would be expected to capture the real population
                   mean?  (note the Figure 7.7 in text).

            B.    How many did you find that captured the real population mean?

  4            How would you calculate a confidence interval if you did not know the population parameters for the population of 
                 interest?     

                  Please provide two examples utilizing two previously drawn samples of 20 cards (exclude 10 cards each previous draw).  (get little S and mean)

        B.     Why would the last two confidence intervals likely vary in length,

                   What aspect of the random sample causes the difference (need to read book)?

*finish today will discuss others Wednesday.
