Sample questions asked in the 8th edition of Probability and Statistics for Engineering and Science:
- 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” ( Weed Technology, 2005: 1030–1036) investigated the effects of herbicide formulation on spray atomization. A figure in the paper suggested the normal distribution with mean 1050 ?m and standard deviation 150 ?m 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 1500 ?m ? At least 1000?m ? b. What is the probability that the size of a single droplet is between 1000 ?m and ? c. How would you characterize the smallest 2% of all droplets? d. If the sizes of five independently selected droplets are measured, what is the probability that at least one exceeds 1500?m?
- A study of the properties of metal plate-connected trusses used for roof support (“Modeling Joints Made with Light- Gauge Metal Connector Plates,” Forest Products J., 1979: 39–44) yielded the following observations on axial-stiffness index (kips/in.) for plate lengths 4, 6, 8, 10, and 12 in: Does variation in plate length have any effect on true average axial stiffness? State and test the relevant hypotheses using analysis of variance with ? = .01. Display your results in an ANOVA table.
- Each front tire on a particular type of vehicle is supposed to be filled to a pressure of 26 psi. Suppose the actual air pressure in each tire is a random variable— X for the right tire and Y for the left tire, with joint pdf a. What is the value of K ? b. What is the probability that both tires are underfilled? c. What is the probability that the difference in air pressure between the two tires is at most 2 psi? d. Determine the (marginal) distribution of air pressure in the right tire alone. e. Are X and Y independent rv’s?
