What is the mean number of rolls of a die before a 1 is observed?

1- Obtain a point estimate of the mean number of rolls of a die before a 1 is observed.

2- The population standard deviation for the number of rolls before a 1 is observed. Use this result to construct a 90% Z-interval for the mean number of rolls required before a 1 is observed.

3- The population mean number of rolls before a 1 is observed is 6. Does your interval include 6? What proportion of the Z-intervals in the class included 6? How many did you expect to include 6?

4- Construct a 90% t-interval for the mean number of rolls required before a 1 is observed.

5- The population mean number of rolls before a 1 is observed is 6. Does your interval include 6? What proportion of the t-intervals in the class includes 6? How many did you expect to include 6?

6- Compare the Z-interval with the t-interval. Which has the smaller margin of error? Why?
