Automobile racing, high-performance driving schools, and driver education programs run by automobile clubs continue to grow in popularity. All these activitiesrequire the participant to wear a helmet that is certified by the Snell Memorial Foundation, a not-for-profit organization dedicated to research, education,testing, and development of helmet safety standards. Snell "SA" (Sports Application) rated professional helmets are designed for auto racing and provideextreme impact resistance and high fire protection. One of the key factors in selecting a helmet is weight, since lower weight helmets tend to place less stresson the neck. The following data show the weight and price for 18 SA helmets (SoloRacer website).Weight (oz)646464645847495966585852526362546363A.Impact Racing Super SportZamp FSA-1Zamp RZ-2Zamp RZ-2 FerrariZamp RZ-3 SportZamp RZ-3 Sport PaintedBell M2Bell M4Bell M4 ProG Force Pro Force 1G Force Pro Force 1 Grafxa.

Did the estimated regression equation provide a good fit? Explain. Hint: If r² is greater than 0.70, the estimated regression equation provides a good fit.7² is(to 3 decimals), the estimated regression equation provideda good fit.

The data shows the price and weight for 18 SA helmets.c. By using the EXCEL, the regression equation is obtained below: Enter the data > Data > Data Analysis > Regression > Ok > Select Y range as B1:B19, X ranges as A1:A19 > Mark Labels > Ok. The output is, From the output, the estimated regression equation is Price^=1928.57+-26.55Weight.e. From the output, the coefficient of determination r2 is 0.718. Thus, the value of r2 is 0.718.
