You interview a random sample of 4 people and they give you the following responses.

You are interested in the linear relationship between annual income and monthly rent they pay. You believe the relationship takes the following form

rent=+ income+

You have the following data

Name	Annual Income (10,000$)	Monthly Rent (100$)
Amy	5	8
Bob	3	4
Carl	10	12
Dan	6	6

1. What is the covariance?

2. What is the correlation?

3. What is the slope coefficient, ?

4. What is the intercept coefficient, ?

(Please round your result to the seconddigit after the decimal point.)

Note: In order to make sure your result is accurate, you may want to leave four digits for the middle steps during your calculation, and only round to the second digit at the end.

Same advice applies in general, to other questions as well.
