How does lateral accelerationside forces experienced inturns that are largely under driver controlaffect nausea asperceived by bus passengers? The article Motion Sicknessin Public Road Transport: The Effect of Driver, Route, andVehicle (Ergonomics, 1999: 16461664) reported data on(calculated in accordance with aBritish standard for evaluating similar motion at sea) and. Relevant summary quantities areValues of dose in the sample ranged from 6.0 to 17.6.a. Assuming that the simple linear regression model is validfor relating these two variables (this is supported by theraw data), calculate and interpret an estimate of the slopeparameter that conveys information about the precisionand reliability of estimation.b. Does it appear that there is a useful linear relationshipbetween these two variables? Answer the question byemploying the P-value approach.c. Would it be sensible to use the simple linear regressionmodel as a basis for predicting % nausea when? Explain your reasoning.d. When Minitab was used to fit the simple linear regressionmodel to the raw data, the observation (6.0, 2.50) wasflagged as possibly having a substantial impact on the fit.Eliminate this observation from the sample and recalculatethe estimate of part (a). Based on this, does the observationappear to be exerting an undue influence?
