please use the calculator method ti 83 or 84 Several insurance adjusters were concerned about the unusually high estimates from Fosbert's U-Bet Repair Station. They obtained the following data: Car Number                            1          2          3          4          5          6          7          8 Fosbert's Estimate                 2.1       4.5       6.3       3.0       1.2       5.4       7.3       9.3 Nickles' Estimate                    2.0       3.8       5.9       2.8       1.3       5.0       6.5       8.6 Estimates are in hundreds of dollars. At a .005 level of significance determine whether the adjusters can conclude that Fosbert's is significantly higher than Nickles'. State hypotheses, P-value, and conclusion.
