(B) The slope and the intercept of the regression line always have the same sign. (C) The correlation coefficient and the intercept of the regression line always have the same sign.

Suppose a researcher collects data on the bacterial contamination, measured in colony-forming unit per milliliter, for both upstream and downstream sections of 35 rivers. The data is plotted with upstream bacterial contamination on the horizontal axis and downstream bacterial contamination on the vertical axis. The Scioto River is an outlier in the ?y‑direction. What must be true about this river? The upstream bacterial contamination for this river is much higher or lower than the rest of the rivers in the data set. The downstream bacterial contamination for this river is much higher or lower than other rivers in the data set that have similar upstream bacterial contamination. This river is an influential observation. The downstream bacterial contamination for this river is much higher or much lower than the rest of the rivers in the data set. The absolute value of the residual of this river is large.

I have this much done, but need help with E, i,ii,iii Which asks: Choose a year other than the one from part 2c. A birth year or the first year might be a good choice(I picked 1990) .i. Use the trend line equation to estimate the y-value for the year of your choice. Find the relative change in the y-value for your chosen year compared to the last year’s value you found in part 2c iii. Interpret the meaning of your relative change value. F.Should we use the trend line model to estimate the y-value for 2020? Why or why not? Note: Hey there! Thank you for the question. As you have posted multiple sub-parts, we have helped you solve the first three parts, according to our policy. Please re-post the other parts with complete background information. Step 2 Calculation: As it is required to build a scatterplot with a trendline, we need to use Excel, where this feature is available. The independent or predictor variable is year, which we have denoted as x, and the dependent…

5. True or False a) The correlation coefficient will always be negative when the slope of the line of best fit is negative. Explain your reasoning. Line B: y = 4x - 6 b) Two lines of best fit have these equations: Line A: y = 2x + 4 Joe says that line B has a stronger correlation since it has a greater slope. Explain. c) Merner's golf drives have a mean distance of 200 m with a standard deviation of 5 m, while Phillip's golf drives have a mean distance of 215 m with a standard deviation of 25 m. Merner is a better golfer than Philips since he is more consistent and has a higher average drive distance.
2. You need to present data to your boss and an assistant gives you a scatter gram with random points. They do not seem to form a line but r = 0.95. You did not draw the graph or calculate r. You do have the original data in front of you and it is accurate. How would you handle the discrepancy between the scatter gram and value for r?
