(a) What is the equation of the regression line for predicting clutch size based on snout-vent length? (Let x - snout vent length and y - clutch size. Round your intercept to two decimal places and your slope to three decimal places.) (b) What is the value of the estimated standard deviation of b? (Round your answer to three decimal places.) (c) Is there sufficient evidence to conclude that the slope of the population line is positive? O No. Since the estimated slope is pasitive and since the P-value is small we do not have convincing evidence that the slope of the population regression line is positive. O Yes. Since the estimated slope is positive and since the P-value is small we have convincing evidence that the slope of the population regression line is positive. O Yes. Since the estimated slope is positive and since the P-value is large we have convincing evidence that the slope of the population regression line is positive. O No. Since the estimated slope is positive and since the P value is large we do not have convincing evidence that the slope of the population regression line is positive.

(a) What is the equation of the regression line for predicting clutch size based on snout-vent length? (Let x - snout vent length and y - clutch size. Round your intercept to two decimal places and your slope to
three decimal places.)
(b) What is the value of the estimated standard deviation of b? (Round your answer to three decimal places.)
(c) Is there sufficient evidence to conclude that the slope of the population line is positive?
