The accompanying data on algae colony density (y) and rock surface area (x) for nine rivers is a subset of data that come from a X 49 55 50 79 37 60 45 49 152 48 27 35 38 171 13 185 23 LA USE SALT (a) Find the equation of the least squares line, (Round your answers to four decimal places.) (b) What is the value of 2 for this data set? (Round your answer to four decimal places.) 2946 Write a sentence interpreting this value in context, (Round your answer to two 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 s. for this data set? (Round your answer to five decimal places.) Write a sentence interpreting this value in context. All observations are exactly s. 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 be S. below the least squares regression line on average. . Observations tend to deviate from the least squares regression line by the value of 2s typically. All observations are exactly 25 from the least squares regression line. (d) Is the linear relationship between rock surface area and alnae colony density nositive or nenative? Is it weak moderate_or strong? Justify your answer 12:17 Mostly clear Search 3/1/20
