Can you please help me on questions 17 through 19? Thank you! 17. A researcher wishes to determine whether the rate of water flow (in liters per second) over an experimental soil bed can be used to predict the amount of soil washed away (in kilograms). The researcher measures theamount of soil washed away for various flow rates, and from these data calculates the least-squares regression line to beAmount of eroded soil = 0.4 + 1.3 x (flow rate)What do we know about the correlation between amount of eroded soil and flow rate?Or= 1/1.3Or= 0.4O It would be positive, but we cannot determine the exact value.O It would either be positive or negative. It is impossible to say anything about the correlation from the information given.18. A group of college students believes that herbal tea has remarkable powers. To test this belief, they make weekly visits to a local nursing home, where they visit with the residents and serve them herbal tea.
