Question

I couldn't include the options for the graphs because it only allows me to add two pictures.

Automobile racing, high-performance driving schools, and driver education programs run by automobile clubs continue to grow in popularity. All these activities require
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 provide extreme 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 stress on the neck. The following data show
the weight and price for 18 SA helmets (SoloRacer website).

The correct scatter diagram is Select your answer V
b. Does there appear to be any relationship between these two variables?
There appears to be a Select your answer - ✓ linear relationship between the two variables. The heavier helmets tend to be -Select your answe ✓expensive.
c. Develop the estimated regression equation that could be used to predict the price given the weight (to 2 decimals). Enter negative values as negative numbers.
