April 25 2023 at 4 30 PM At a plant that manufactures bars of steel a machine is used to cut the bars to specific lengths The machine has a dial that sets the length of the bars to be cut However the dial is currently out of alignment and the plant manager is collecting data to assess the situation The following table shows 8 trials at different dial settings along with the actual output length of the bars that were cut All measurements are in millimeters the test statistic for the appropriate test is t 9 018 Does the data provide convincing statistical evidence that there is a linear relationship between output length and dial setting
