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? (Round your answer to four decimal places.)(c) How would you characterize the smallest 2% of all droplets? (Round your answer to two decimal places.)The smallest 2% of droplets are those smaller thanum in size.(d) If the sizes of five independently selected droplets are measured, what is the probability that at least one exceeds 1365 μm? (Round your answer to four decimal places.)

Please rearrange the following steps of Multiple Linear Regression so that they are in order from the first step to the last step. 1. Review the Variance Inflation Factor values and use a backward-elimination process to remove the variable with the largest VIF above 10 and refit the model with the remaining x-variables and reassess the new VIF values. 2. Check the residuals for the final model to determine if they are normally distributed¸ have random scatter¸ and have constant variance. 3. Perform a 6-step ANOVA test to determine if at least one x-variable in the full model is useful for predicting the y-variable. 4. Use the backward-elimination procedure to remove any unneeded x-variables from the model to obtain the reduced model. 5.Create scatterplots of each x-variable with the y-variable to assess the assumption linearity and confirm by checking correlations.

An engineer measures the peak current (in microamps) when a solution containing an amount of nickel (in parts per 10°) is added to a buffer. The experiment was repeated for eleven different values of nickel solutions. A scatterplot showing the data is given below: Peak Current in Eleven Buffers with Added Nickel Solutio 60 120 140 100 Amount of nickel (pp million) Suppose a regression line was added to the plot above. If an additional measurement had been taken with the nickel of 62 parts per 10 and a peak current of 0.38 microamps, adding this observation would: O A. increase the intercept, decrease the slope. OB. increase the intercept, increase the slope. C. decrease the intercept, increase the slope. OD. decrease the intercept, decrease the slope. E. not affect the regression line.
