The table below shows the traffic fatality rate R, in fatalities per 100 million vehicle miles traveled, t years after 2010.t Find the equation of the regression line for Ras a function of t . (Round regression line parameters to two decimal places.) I t = years since 2010 I R = rate 0 1.11 1 1.10 2 1.14 3 1.09 4 1.07 R(t) =

i'm sorry i don't know

step-by-step explanation:

the cost of 6 show tickets is $30.

step-by-step explanation:

look closely at the graph, where it says 6 that's the amount of tickets. go up until you reach the dot. the dot shows that the coordinates are (6, 30). there fore from that you can infer that 6 show tickets cost $30.

answer-

the sum of the residuals for all the points is 0

solution-

while doing a regression analysis our objective is to find a line of best fit. usually all the data points don’t lie exactly on this regression equation line. they are scattered around the line.

a residual represents the difference or variation between the actual or observed value and the predicted value. on the graph, it is the vertical distance between a data point and the regression line.

they are positive if they lie above the regression line and negative if they lie below the regression line. if the regression line actually passes through the point, the residual at that point is zero, i.e the observed value is same as the predicted value.

if the line is actually the line of best fit, then sum of the residuals and their mean is equal to zero.
