Question 1

Compute r, the correlation coefficient, rounded to the nearest thousandth, for the following data:



◦ 0.75
◦ -0.905
◦ 0.905
◦ -0.75

Question 2

Use the following data to a. determine the coefficient of correlation, rounded to the nearest thousandth, b. find the equation of the regression line for time watching TV and time on the Internet, c. approximate how much time on the Internet can we predict for a person who spends 10 hours weekly watching TV.


◦ a. r = -0.752   b. y = -1.52x + 5.25   c. 9.9 hours
◦ a. r = 0.752   b. y = 1.52x - 5.25   c. 10 hours
◦ a. r = -0.752   b. y = 5.25x + 1.52   c. 54 hours
◦ a. r = 0.752   b. y = 1.52x + 5.25   c. 20.5 hours

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
