A group of advisors have been provided with the following set of data.

Time (days ) Distance (Km) Uncertainty in distance (km5254.88311.310185.411271.013154.814211.516117.319171.8Each advisor plots the data and draws a best fit line as shown below (Notice how the first

data point, 25.0 4.8 km, is shown as an error bar that extends from 20.2 km to 29.8 km on the graph).

Which advisors line do you think is a better fit to the data?

Advisor A or Advisor B? Why? Advisor B or Advisor C? Why? Advisor A or Advisor D? Why?What feature of a data points position on the graph relative to the best fit line and/or the size ofan error bar do you feel influence the best fit line? How does our previous work on uncertainty(standard deviation and uncertainty in a slope) and comparisons (t- score) provide insight intoyour thoughts?
