Answer to Question #334702 in Statistics and Probability for edd

Question

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 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 um and standard deviation 150 um was a reasonable model for droplet size for water (the "control treatment") sprayed through a 760 ml/min nozzle.

(a) What is the probability that the size of a single droplet is less than 1365 um? At least 925 um? (Round your answers to four decimal places.)

less than 1365 um

at least 925 um

(b) What is the probability that the size of a single droplet is between 925 and 1365 pm? (Round your answer to four decimal places.)
