Hawk thinks his heartrate will increase as he increases his skateboarding speed. To see if this relationship exists, he records six different speeds and models it with a scatterplot and regression output.A scatterplot is shown with the x axis labeled Speed, miles per hour, and the y axis labeled Pulse, beats per minute. The points on the graph increase from 9.5 and 68 to 15.8 and 116.Regression StatisticsMultiple R 97.28153%R Square 94.63696%Adjusted R Square 93.29620%Standard Error 4.806846736Observations 6 df SS MS FRegression 1 1,630.910231 1,630.910231 70.58453Residual 4 92.42310217 23.10577554 Total 5 1,723.333333 Coefficients Standard Error t Stat p-ValueIntercept 1.301246992 10.66036651 0.122064001 0.908735Speed 7.315685846 0.870763656 8.401459797 0.001098Part A: Write the equation of the regression line using the regression output.
