How would you describe the relationship between mean call-to-shock time and survival rate? O There is a strong positive relationship. The relationship is close to being linear, particularly if the point with the lowest x value is disregarded. If that point is included then there is the suggestion of a curve. O There is a strong negative relationship. The relationship is close to being linear, particularly if the point with the lowest x value is disregarded. If that point is included then there is the suggestion of a curve. O There is a strong positive relationship. The relationship is close to being linear, particularly if the point with the highest x value is disregarded. If that point is included then there is the suggestion of a curve. O There is a strong negative relationship. The relationship is close to being linear, particularly if the point with the highest x value is disregarded. If that point is included ther there is the suggestion of a curve. (b) Find the equation of the least-squares line. (Round your values to three decimal places.) ŷ = (c) Use the least-squares line to predict survival rate for a community with a mean call-to-shock time of 10 minutes. (Round your answer to three decimal places.)
