An experimenter is studying the effects of temperature, pressure, and type of catalyst on yield from a certain chemical reaction.Two different temperatures, five different pressures, and six different catalysts are under consideration.(a) If any particular experimental run involves the use of a single temperature, pressure, and catalyst, how many experimentalruns are possible?runs(b) How many experimental runs are there that involve use of the lowest temperature and two lowest pressures?runs(c) Suppose that six different experimental runs are to be made on the first day of experimentation. If the six are randomlyselected from among all the possibilities, so that any group of six has the same probability of selection, what is theprobability that a different catalyst is used on each run?

11. Industrial Design At a regional competition for industrial design students, each project submitted is given a score from 1 to 10 in each of three categories: precision, weight = 30%; surface finish, weight = 20%; artistic design, weight = 50%. The total score for the project is found by adding the products of each category score and its weight. %3D %3D a. Stephanie has a precision score of 8, a surface finish score of 7, and an artistic design score of 9. What is her total project score? b. The six finalists have the scores given in the table below.

Experiment 1: An agronomist wanted to compare the yield of three different varieties of rice (A, B, C). So, within a field, he randomly assigned each variety to five plots. The yield[s] in pounds per acre were recorded for each plot. Go back to the original experiment in (1) where we are only interested in variety, not fertilizer. The agronomist realized that he wanted his results to apply over a range of soil conditions. So, he decided to conduct the experiment on 4 different locations (subdivisions) in a field so that the elevation and type of soil vary. He planted each variety on one plot within each subdivision of the field. Again, the yield[s] in pounds per acre were recorded for each plot. (a) What is the response in the study? (b) What is the factor in the study? What are the factor levels? (c) What are the treatments? What are the blocks, if any?
Surgery and germs. Joseph Lister (for whom Listerineis named!) was a British physician who was interestedin the role of bacteria in human infections. He suspectedthat germs were involved in transmitting infection, so hetried using carbolic acid as an operating room disinfectant.In 75 amputations, he used carbolic acid 40 times. Of the40 amputations using carbolic acid, 34 of the patientslived. Of the 35 amputations without carbolic acid,19 patients lived. The question of interest is whethercarbolic acid is effective in increasing the chances ofsurviving an amputation.a) What kind of a study is this?b) What do you conclude? Support your conclusion bytesting an appropriate hypothesis.c) What reservations do you have about the design ofthe study?

To perform a certain type of blood analysis, lab technicians must perform two procedures. The first procedure requires either one or two separate steps, and the second procedure requires either one, two, or three steps.

Cholesterol: An article in the Archives of Internal Medicine reported that in a sample of 245 men, 70 had elevated total cholesterol levels (more than 200 milligrams per deciliter). In a sample of 170 women, 62 had elevated cholesterol levels. Can you conclude that the proportion of men with elevated cholesterol levels is less than the proportion of women with elevated cholesterol levels? Let p₁ denote the proportion of men with elevated cholesterol levels and p₂ denote the proportion of women with elevated cholesterol levels. Use the a= 0.05 level of significance and the P-value method with the TI-84 Plus calculator.

Group problems: The Collision Problem: You have been hired by an insurance investigator to look into an accident involving a sailboat and a speedboat that occurred on New Year's day at 3:00 in the arternoon. Your job is to determine where (relative to the dock) the collision took place. After your investigation you ascertain the following facts about the case. The speedboat was carrying a toup of 20 people who were returning to shore after enjoying a 2-hour picnic on an island. The island is located 5.2 miles east and 12.6 miles north of the dock. The speedboat was heading from the island toward a point on the shore located 3.0 miles due west of the dock. Around the same time, the sailboat left the dock heading toward a buoy that is 5.0 miles west and 7.5 miles north of the dock. Neither boat made it to its destination since they collided in the water. You interviewed 5 witnesses and 2 lifeguards for 4 hours, in addition to studying nautical maps provided by the Navy.

Pesticides A study published in 2002 in the journalEnvironmental Health Perspectives examined the genderratios of children born to workers exposed to dioxin inRussian pesticide factories. The data covered the yearsfrom 1961 to 1988 in the city of Ufa, Bashkortostan,Russia. Of 227 children born to workers exposed todioxin, only 40% were male. Overall in the city of Ufa, the proportion of males was 51.2%. Is this evidencethat human exposure to dioxin may result in the birth of more girls? (An interesting note: It appeared that pater-nal exposure was most critical; 51% of babies born to mothers exposed to the chemical were boys.)

1. Susan Sound predicts that students will learn most effectively with a constant background sound, as opposed to an unpredictable sound or no sound at all She randomly divides twenty-four students into three groups of eight. All students study a passage of text for 30 minutes. Those in group 1 study with background sound at a constant volume in the background. Those in group 2 study with noise that changes volume periodically. Those in group 3 study with no sound at all. After studying, all students take a 10 point multiple choice test over the material. Their scores follow test scoresS group 7 46 86 629 5 5 3 4 4 7 2 2 2 471 2 1 5 5 1) constant sound 2) random sound 3) no sound
2-18. Wyoming Electric Coop owns a steam-turbine power-generating plant. Because Wyoming is rich in coal deposits, the plant generates its steam from coal. This, however, may result in emission that does not meet the Environmental Protection Agency (EPA) standards. EPA regulations limit sulfur dioxide discharge to 2000 parts per million per ton of coal burned and smoke discharge from the plant stacks to 20 lb per hour. The Coop receives two grades of pulverized coal, Cl and C2 for use in the steam plant. The two grades are usually mixed together before burning. For simplicity, it can be assumed that the amount of sulfur pollutant discharged (in parts per million) is a weighted average of the proportion of each grade used in the mixture. The following data is based on the consumption of 1 ton per hr of each of the two coal grades. Coal grade CI Sulfur discharge in parts per million 1800 2100 Smoke discharge in Ib per hour 2.1 9 Steam generated in lb per hour 12,000 9,000 (a) Determine…
