Box, Hunter, and Hunter have analyzed the dispersion of an aerosol spray as a function of its age. The dispersion y is measured as the reciprocal of the number of particles in a unit volume. Age x is measured in minutes. The experiments were performed in random order, but their results are listed here in increasing order of x:

Age, x	Dispersion, y
8	6.16
22	9.88
35	14.35
40	24.06
57	30.34
73	32.17
78	42.18
87	43.23
98	48.76

Find a 95% prediction interval estimate of the dispersion for an individual aerosol

spray of age 90.

Which of the interval in h) and i) is the widest? Explain why.

Find the correlation coefficient.

You and your partner treasure hunter have uncovered a box of coins from the ancient civilization of Hyrule. The box contains 2 big coins, 3 silver coins, 4 shiny coins, and 5 tiny coins! The two of you decide to split the contents of the box evenly. You and your partner flip a coin and decide that you will have the hard job of being the divider. Then your partner will pick the pile they value more. You took a...

Two students in your class, Hunter and Maggie, are disputing a function. Hunter says that for the function, between x = –2 and x = 2, the average rate of change is 0. Maggie says that for the function, between x = –2 and x = 2, the graph goes up through a turning point, and then back down. Explain how Hunter and Maggie can both be correct, using complete sentences.

Continuous data sets can be analyzed for measures of central tendency, dispersion, and quartiles. Discuss the importance of reviewing these measures and identify the full story that these measures reveal about the data that is relevant to the business. Provide a relevant example to illustrate your ideas. In replies to peers, discuss whether you agree or disagree with the examples provided and justify your ideas.

Explain how liquids can be analyzed by gas chromatography. Briefly define or describe the function, in gas chromatography, of the carrier gas: stationary liquid phase: solid support: If ethyl acetate and n-butyl acetate are analyzed by gas chromatography, which of these esters will generally produce a peak with the shorter retention time? What operating variables determine retention time? Explain why is it important to inject the sample quickly.

Crime scene investigators have determined that an acrylic spray paint (polymethylmethacrylate, PMMA) was used to deface the Mona Lisa. Leonardo used linseed oil. We would like a solvent that interacts more strongly with acrylic than with linseed oil. Based on their chemical structures, we can approximate the SSCED parameters of linseed oil as n-hexadecane and acrylic paint as methylethylketone. Do you recommend CHCl_3, toluene, or acetone as the solvent? Explain.

Assume that you have a box of resistors that have a Gaussian distribution of resistances with mean µ = 100 Ω and standard deviation σ = 20 Ω (i.e., 20% resistors). Suppose that you wish to form a subgroup of resistors with µ = 100 Ω and standard deviation 5 Ω (i.e., 5% resistors) by selecting all resistors with resistance between the two limits r1 = µ−a and r2 = µ+a. (Apparently, you are too cheap to just order the...

Clinical studies of 1,000 people were analyzed to determine if they have a gene that predisposes people to skin cancer. That study revealed that the probability that a person has the gene predisposed to contract cancer is 01. a) Calculate the probability that 4 or more people will have to be tested before two people are detected with the gene. b) On average, how many people must be analyzed for 2 people to be detected with the gene.

Clinical studies of 1000 people were analyzed to determine if they have a gene that predisposes people to have skin cancer. That study revealed that the probability that a person has the gene predisposed to contract cancer is 0.1. a) Calculate the probability that 4 or more people have to be analyzed before two people are detected with the gene. b) On average, how many people must be analyzed for 2 people to be detected? with the gene.
