Question 733096: Based on the this problem, can you approximate a line of best fit by writing an equation? Use t for packing time and s for the number of shipments packed.
The original question is: The table shows the relationship between the number of shipments packed and the time spent packing for a group of workers at a mail order company.
Minutes spent packing: 30 45 60 75 90
Shipments packets: 244 342 490 619 705
Plot the date points: This has been answered in the graph provided.
b. Are there any points that Outliers? If so, what possible explanation could there be for the existence of this discrepancy from the other data?

I plotted the points and found the least squares regression equation.
#of packets(t) = 7.99t + 0.4
----
p(2) = 7.99*2 + 0.4 = 16.38 packets
------------------------------------------
b. Are there any points that Outliers?
Ans: No

If so, what possible explanation could there be for the existence of this discrepancy from the other data?
Ans: Erroneous data entry.
