Spray drift is a constant concern for pesticide applicators and agricultural producers. The inverse relationship between droplet size and drift potential is well known in the literature. Researchers investigated the effects of herbicide formulation on spray atomization and found that droplet sizes of 1050 um with a standard deviation of 150 um was a reasonable model for droplet size sprayed through a 760 ml/min nozzle. . What is the probability that the size of a single droplet is less than 1500 um? . What is the probability that the size of a single droplet is at least 1000 um? . What is the probability that the size of a single droplet is between 1000 and 1500 um? . What is the sizing of droplets associated with the smallest 2% of all droplets? . If the sizes of five independently selected droplets are measured, what is the probability that exactly two of them exceed 1500 um
