Spray drift is a constant concern for pesticide applicators and agricultural producers. The inverse relationship betweendroplet size and drift potential is well known. The paper "Effects of 2,4-D Formulation and Quinclorac on Spray Droplet Sizeand Deposition"+ investigated the effects of herbicide formulation on spray atomization. A figure in a paper suggested thenormal distribution with mean 1050 µm and standard deviation 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 1395 µm? At least 925 µm? (Round youranswers to four decimal places.)less than 1395 μmat least 925 μm(b) What is the probability that the size of a single droplet is between 925 and 1395 μm? (Round your answer tofour 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 oneexceeds 1395 μm? (Round your answer to four decimal places.)

The drainage loading on a stormwater collection system is normally distributed with mean 1.2 million gallon per day (MGD) and standard deviation 0.4 MGD. Compute the system capacity, i.e., Design Life level (DDL), of the systems with a design life of 15 years and maximum risk of failure of 0.15 over its design life
Suppose the flow of current (milliamps) in wire strips of a certain type under specified conditions can be modeled with a normal distribution having mu (mean) = 20 and sigma (SD) = 1 (hint: think about how the corresponding density curve relates to the standard normal curve). What proportion of strips will have of between 18.5 and 22 milliamps?
According to the National Center for Health Statistics, the distribution of height for 16-year-old females is modeled well by a Normal density curve with mean μ = 64 inches and standard deviation o = 2.5 inches. Assume this claim is true for the three hundred 16-year-old females at a large high school. To see if this claim is true at their high school, an AP® Statistics class chooses an SRS of twenty 16-year-old females at the school and measures their heights. In their sample, the mean height is 64.7 inches. We used technology to simulate choosing 250 SRSs of size n = 20 from a population of three hundred 16-year-old females whose heights follow a Normal distribution with mean μ = 64 inches and standard deviation o = 2.5 inches. The dotplot shows x = the sample mean height for each of the 250 simulated samples. 62.0 62.5 63.0 63.5 64.0 64.5 65.0 65.5 x = simulated sample mean height (in.) 66.0 Would it be surprising to get a sample mean of x = 64.7 or larger in an SRS of size 20 when…

Strength of concrete: The compressive strength, in kilopascals, was measured for concrete blocks from five different batches of concrete, both three and six days after pouring. The data are as follows. Can you conclude that the mean strength after three days differs from the mean strength after six days? Let μ1 represent the mean strength after three days and =μd−μ1μ2 .

A company claims that the mean monthly residential electricity consumption in a certain region is more than 860 kiloWatt-hours (kWh). You want to test this claim. You find that a random sample of 69 residential customers has a mean monthly consumption of 880 kWh. Assume the population standard deviation is 126 kWh. At α=0.01, can you support the claim? Complete parts (a) through (e). Also find the critical values.

A random sample of 41 adult coyotes in a region of northern Minnesota showed the average age to be x = 2.09 years, with sample standard deviation s = 0.83 years. However, it is thought that the overall population mean age of coyotes is μ = 1.75. Do the sample data indicate that coyotes in this region of northern Minnesota tend to live longer than the average of 1.75 years? Use α = 0.01. Solve the problem using the critical region method of testing (i.e., traditional method). (Round your answers to three decimal places.) test statitics= critical=
