Spray drift is a constant concern for pesticide applicators and agricultural producers. The inverse relationship between droplet size and drilt potential is well known. The paper "Effects of 2,470 Formulation and Quinclorac 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 pm and standard deviation 150 pm was a reasonable model for droplet size for water {the "control treatment") sprayed through a 760 mllmin nozzle. I USE SA (a) What is the probability that the size of a single droplet is less than 1395 pm? At least 900 pm? (Round your answers to four decimal places.) less than 1395 pm [19893 J at least 900 pm 08306 X (b) What is the probability that the size of a single droplet is between 900 and 1395 pm? (Round your answer to four decimal places.) 742 5 X (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 than 0.010? X pm in size. (d) If the sizes of ve independently selected dropleE are measured, what is the probability that at least one exceeds 1395 pm? (Round your answer to four decimal places.) 0 0233 x You may need to use the appropriate table in the Appendix of Tables to answer this question. Need Help? _
