- Grass buffer strips are grassy areas that are planted between bodies of water and agricultural fields. These strips are designed to filter out sediment, organic material, nutrients, and chemicals carried in runoff water. The figure [SEE PHOTO A] below shows a cross-sectional view of a grass buffer strip that has been planted along the side of a stream. A study in Nebraska investigated the use of buffer strips of several widths between 5 feet and 15 feet. The study results indicated a linear relationship between the width of the grass strip (x), in feet, and the amount of nitrogen removed from the runoff water (y), in parts per hundred. The following model was estimated. yˆ = 33.8 + 3.6x (a) Interpret the slope of the regression line in the context of this question. (b) Would you be willing to use this model to predict the amount of nitrogen removed for grass buffer strips with widths between 0 feet and 30 feet? Explain why or why not.

Using the same dates makes the second sample dependent on the first and reduces variability in water clarity attributable to date. B. Using the same dates maximizes the difference in water clarity. C. Using the same dates makes it easier to remember to take samples. D. Those are the same dates that all biologists use to take water clarity samples. b) Does the evidence suggest that…arrow_forward

- aylor Swift wants to know the proportion of her fans who listened to her new single ME! within the first hour of it being released. In order to estimate this, she takes a sample of 150 of her fans and asks them if they listened to the song in this time period. Of the 150 fans, 135 of them (90%) responded that they did listen to the song during this time period. What is the parameter and what is its value? a. The parameter is the proportion of the 150 sampled Taylor Swift fans who listened to ME! within the first hour after it released, which is 135. b. The parameter is the group of Taylor Swift fans who were surveyed, which is 150. c. The parameter is the proportion of all Taylor Swift fans who listened to ME! within the first hour after it released, which is unknown. d. The parameter is the proportion of all Taylor Swift fans who listened to ME! within the first hour after it released, which is 0.9. e.
