    The shape of “Data B” is:

In the following situation, indicate what type of sampling technique was used: A certain county is comprised of 5 cities and wishes to determine if the citizens of the county think that there needs to be more funding for education.  To determine this, the county is divided up into its 5 cities and a random sample of 100 is taken from each city.

If a bar code is 9 digits long, how many possible bar codes are there if repetition is allowed?

A police department tracks the number of burglaries that occur each day for a 100 day period.  The following probability distribution represents the number of burglaries each day and their corresponding probabilities.  Using this, find the mean of the probability distribution.   X 0 1 2 3   P(x)   40100{“version”:”1.1″,”math”:”40100″}   50100{“version”:”1.1″,”math”:”50100″}   9100{“version”:”1.1″,”math”:”9100″}   1100{“version”:”1.1″,”math”:”1100″}  

    For “Data A” the median is __________ the mean.  Fill in the blank with the correct answer:
