Show ALL work!  Either write your work in the space provided or attach spreadsheets.

Please refer to Math215_Cond_Probability.ppt for questions 4 and 8.  Other exam questions are review from previous chapter slides.

1.  Calculate the sample standard deviation for the following set of numbers.

45, 81, 26, 43, 20, 90, 450, 340, 34, 67, 11

2.  For the data set shown in question #2, for which you have calculated the standard deviation, what is the z-Score for the number 90?

3.  For the following graph, would you estimate the correlation to be positive, negative or neutral.  Please explain your answer.

4.  Event A: Selecting a Queen from a standard deck of cards.

The Queen is replaced back into the deck.

Event B: Selecting a 2 card from the same deck of cards.

What is P(B|A), that is, the probability of event B, given that event A occurred?

Are events A and B related, meaning is event B dependent in any way on event A?

5.  Calculate the correlation coefficient for the following data set.

6.  Henry sells boats.  Find below a list of boat sales for Henry.  What is the expected value for Henry's boat sales?

7.  Calculate the probability that a standard normal random variable is between 0 and  1.55

8.  Event A: Selecting a Jack from a standard deck of cards.

The Jack is NOT replaced back into the deck.

Event B: Selecting a 5 card from the same deck of cards.

What is P(B|A), that is, the probability of event B, given that event A occurred?

Are events A and B related, meaning is event B dependent in any way on event A?
