Spray drift is a constant concern for pesticide applicators and agricultural producers. The inverse relationship between droplet size and drift potential is well known. The paper "Effects of 2,4-D Formulation andQuinclorac on Spray Droplet Size and Deposition"+ investigated the effects of herbicide formulation on spray atomization. A figure in a paper suggested the normal distribution with mean 1050 μm and standarddeviation 150 μm was a reasonable model for droplet size for water (the "control treatment") sprayed through a 760 ml/min nozzle.USE SALT(a) What is the probability that the size of a single droplet is less than 1365 μm? At least 975 μm? (Round your answers to four decimal places.)less than 1365 μmat least 975 μm(b) What is the probability that the size of a single droplet is between 975 and 1365 μm?

Consider a linear regression model for the decrease in blood pressure (mmHg) over a four-week period with muy=2.8+0.8x and standard deviation chi=3.2. The explanatory variable x is the number of servings fruits and vegetables in a calorie-controlled diet. The decrease in blood pressure y will vary about this subpopulation mean. What is the distribution of y for this subpopulation?
Seedlings of understory trees in mature tropical rainforests must survive and grow using intermittent flecks of sunlight. How does the length of exposure to these flecks of sunlight (fleck duration) affect growth? Researchers experimentally irradiated seedlings of the Southeast Asian rainforest tree with flecks of light of varying duration while maintaining the same total irradiance to all the seedlings. Below is the data. Fit a linear model to the data.

Given the relatively small sample size, we can characterize the left-hand plot as a random cloud of points in a rough horizontal band and the right-hand plot as points that lie reasonably close to the 45° line. Briefly describe what this tells us about the simple linear regression model assumptions in this case. The largest absolute standardized residual for this simple linear regression analysis is 1.298, while the highest leverage is 0.430. Briefly describe what this tells us about potentially influential observations in this analysis.
Acrylamide is a chemical that is sometimes found in cooked starchy foods and which is thought to increase the risk of certain kinds of cancer. The paper "A Statistical Regression Model for the Estimation of Acrylamide Concentrations in French Fries for Excess Lifetime Cancer Risk Assessment"+ describes a study to investigate the effect of frying time (in seconds) and acrylamide concentration (in micrograms per kilogram) in french fries. The data in the accompanying table are approximate values read from a graph that appeared in the paper.

"Durable press" cotton fabrics are treated to improve their recovery from wrinkles after washing. "Wrinkle recovery angle" measures how well a fabric recovers from wrinkles. Higher is better. Here are data on the wrinkle recovery angle (in degrees) for two types of treated fabrics: Permafresh 15 12 16 13 11 14 10 Hylite 16 20 18 15 19 A manufacturer wants to know how large is the difference in mean wrinkle recovery angle.
