Data has been collected on two tools wsed in a manufacturing lathe process The length ofme that the toel can be used before it has to be replaced is known as its lhfetume The lifetime (1is thought to be shorter as the speed of the lathe C) increaces There are twenty total observahions each tool type (A vs. B) Lifetime Speed Teel Lidetine Speed Teol 18.73 610 452950A 1743 1 720-1-A-12540-1-tso 1434 840 1344 980 016670 2709 770 26051000 33.49 2439 530 A 3562590 B 13 34 1.6801 A 22 71 540 26 071 9101 B 36.78 650 19 45 1268 890 $10 1932 730 we-oduced the statist cal Auctions Sry and su 4347 asapnment The "best ft" line given by Extra Credit Opportunity Page 1 And it can be computed using Sxy and Sx SEx A meaure of how good a fit is given by the sum of squared enrors (SSE) Problem 1.(8 points).Plot te lifetimes (10) as a fuction of the lathe speed C0.Then th full set of twenty data poists to fit (using formulas provided) and plot the fetimes (C as a function of the lathe speed CXD, Fanally, seport on the eoalts by compuing the SSE for the Smed
