Mean call-to-shock time, 26 79 12 Survival rate, y 91 44 32 44 LA USE SALT (a) Construct a scatterplot for these data 10 12 10 10 12 100 How would you describe the relationship between mean call-to-shock time and survival rate? There is a strong positive relationship. The relationship is close to being linear, particularly if the point with the lowest value is disregarded. If that point is included then there is the suggestion of a curve There is a strong negative relationship. The relationship is close to being linear particularly if the point with the lowest value is disregarded. If that point is included then there is the suggestion of a curve There is a strong positive relationship. The relationship is close to being linear, particularly if the point with the highest value is disregarded. If that point is included then there is the suggestion of a curve There is a strong negative relationship. The relationship is close to being linear particularly if the point with the highest value is disregarded. If that point is included then there is the suggestion of a curve (b) Find the equation of the least-squares ine. (Round your values to four decimal places) (c) Use the least squares line to predict survival rate for a community with a ean call-to-shock time of 8 minutes. (Round your answer to three decimal places)
