## Question

###### Use the formula for the regression line to predict the mileage for vehicle that weighs 4000 pounds:Can we be very confident; moderately confident; not at all confident that this prediction dose t0 the actual mileage? Explain:Compare vour answers about your confidence for parts â‚¬ and f Do vou think they agree? Explain:Explain the trend context of the graph: Does this make sense? Explain.the association strong; moderate wcak?Plug the value =0 into the cquation and find the valuc for y- That is t

Use the formula for the regression line to predict the mileage for vehicle that weighs 4000 pounds: Can we be very confident; moderately confident; not at all confident that this prediction dose t0 the actual mileage? Explain: Compare vour answers about your confidence for parts â‚¬ and f Do vou think they agree? Explain: Explain the trend context of the graph: Does this make sense? Explain. the association strong; moderate wcak? Plug the value =0 into the cquation and find the valuc for y- That is the "v- intercept" Find and interpret the value of the y-Intercept here by writing sentence using the names and units of the variables and this Vaiuc Use this sentence: "For . vehicle that weighs pounds, our model predicts that the will be (number) (units) (variable] (number) (units] Does the y-intercept make sense the context of this problem? Explain: Note: This doesn't mean the model = wrongl The model requires an anchor" value for the explanatony variable of zero, which often doesn"t fit inside the valid interval (Think carefully about the equation and ser whether you can tell wthout doing any computation ) What charges predicted value of mPB wnen YOU change from 4000 - 4D01 pounds? Do you have compute values to find this? callthe number multiplied by the explanatory variable (x] the slope; The interpretation of the slope When the value of x increases by unit, then the predicted value of y changes bv Wnits Rewrite this sentence using the numerical value of the slope, the names af tha two variables; and the units of the two variables:
