(Round your answers to three decimal places.) y = (b) What is the value of 2 for this data set? (Round your answer to three decimal places.) Write a sentence interpreting this value in context. (Round your answer to one decimal place.) % of the variability in algae colony density can be explained by the approximate linear relationship between algae colony density and rock surface area. (c) What is the value of Se for this data set? (Round your answer to three decimal places.) Write a sentence interpreting this value in context. All observations are exactly 2se from the least squares regression line. All observations are exactly Se from the least squares regression line. Observations tend to deviate from the least squares regression line by the value of Se typically. Observations tend to deviate from the least squares regression line by the value of 25 . typically. Observations tend to be se below the least squares regression line on average. (d) Is the linear relationship between rock surface area and algae colony density positive or negative? Is it weak, moderate, or strong? Justify your answer. The relationship between rock surface area and algae colony density is ---Select--- |because the slope of the regression line is ---Select--- .
