1	_________ Calculate the slope of the least squares line for the current and voltage.
2	_________ Calculate the y-intercept of the least squares line for the for the current and voltage data.
3	_________ What does of the sign of the slope tell us about this data? That is, what type of correlation is this?
4	_________ What is the predicted voltage for a current of 4 amps (for this calculation, presume that the relationship remains linear beyond 2 amps)?
5	_________ What is the predicted current for a voltage of 20 volts (for this calculation, presume that the relationship remains linear beyond 10 volts)?
6	_________ Calculate the linear correlation coefficient r for the the current and voltage.
7	_________ Is the correlation none, low, moderate, high, or perfect?
8	_________ Calculate the coefficient of determination.
9	__________________ What does the coefficient of determination tell us about the relationship between per the current and voltage?
10	__________________ Does the relationship appear to be a linear relationship between the current and voltage?
11	__________________ There are actually two functions involved, one being a linear component. Do you have any idea what the other function might be (nota bene: it helps if you took MS 101...).
