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:

The probability that you win a game is .4 for each play and the plays are independent.  Let X be the number of wins in 15 plays.  What is the probability that you win exactly 4 times in 15 plays?

Suppose you flip a fair coin 10 times and you get 7 heads.  The probability of a head appears to be 7/10.  However, in the long run the probability of a head will be:

The measure of central tendency that is most affected by outliers is the:

A summary measure that is computed from a population to describe a characteristic is called a:

Suppose that you have a bucket full of poker chips.  There are 13 yellow, 14 red, 9 green and 19 blue chips in the bucket.  What is the probability of selecting a yellow chip then a green chip if you pick two chips without replacement?

    A possible correlation coefficient of the data on the scatter plot is:

In the following situation identify the type of study:  Cruise ship passengers are given magnetic bracelets, which they agree to wear in attempt to eliminate or diminish the effects of motion sickness.
