_________ 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. |

__________________ 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? |

__________________ 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...). |
