The invasive diatom species Didymosphenia geminata has the potential to inflict substantial ecological and economic damage in rivers. An article described an investigation of colonization behavior. One aspect of particular interest was whether y colony density was related toxrock surface area. The article contained a scatterplot and summary of a regression analysis. Here is representative data x 50 71 55 50 33 58 79 26 y|154 1931 5024 4 737 9 x 69 44 37 70 20 45 49 yl 271 40 173 15 45 187 27 (a) Fit the simple linear regression model to this data. (Round your numerical values to three decimal places.) (b)Predict colony density when surface area 70 and calculate the correspanding residual. (Round your answers to the nearest whole number.) (c)colony density corresponding resi 71 and calculate the corresponding residual. (Round your answers to the nearest whole number.) (d)Predict colony density when surface area colony density corresponding residual How do the res duals compare? 1. The residual for the first point is positive, while the residual for the second point is negative. 2. The residuals for both points are negative. 3. The residual for the first point is negative, while the residual for the second point is positive. 4. The residuals for both points are positive.

Amountain climber starts a climb at an elevation of 453 feet above sea level at his first rest stop he has climbed 162 feet and by his second rest stop he has climbed another 207 feet its getting late in the day so the climber starts his way down if the climber desends 285 feet how much does he need to ascend or descend to return to the original starting point
