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 lov weight helmets tend to place less stress on the neck. The following data show the weight and price for 18 SA helmets (SoloRacer website).

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 answer - * 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. Price = Weight + d. Test for the significance of the relationship at the 0.05 level of significance. p-value corresponding to F test is - Select your answer - p-value corresponding to t test on B1 (coefficient of Weight) is - Select your answer - There - Select your answer - + evidence of a significant relationship. e. 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. p2 is (to 3 decimals), the estimated regression equation - Select your answer - a good fit.
