A technician suspects that one or more of the processors in a distributed system is not working properly. The processors, A, B, and C, are all capable of reporting information about the status (working or not working) of the processors in the system. The technician is unsure whether a processor is really not working, or whether the problem is in the status reporting routines in one or more of the processors. After polling each processor, the technician receives the following status reports: • Processor A reports that processor B is not working and processor C is working. • Processor B reports that A is working if and only if B is working. Processor C reports that at least one of the other processors is not working.

Students at the University of Alabama use the following modes of transportation: bike, car, and bus. A survey of 720 students finds that the numbers of students who use each mode of transportation are as follows: 309, bike240, car330, bus120, bike and car138, car and bus150, bike and bus84, all three modes How many of the surveyed students use EXACTLY ONE of these modes of transportation? students

The college newspaper of a large Midwestern university periodically conducts a survey of students on campus to determine the attitude on campus concerning issues of interest. Pictures of the students interviewed, along with quotes of their responses, are printed in the paper. Students are interviewed by a reporter “roaming” the campus who selects students to interview “haphazardly.” On a particular day the reporter interviews five students and asks them if they feel there is adequate student parking on campus. Four of the students say no. The sample proportion  that respond “no” is thus 0.8. Reference: Ref 12-3 Referring to the information above, the standard error of  is Select one: a. 0.8. b. 0.64. c. 0.4. d. 0.18. e. 0.032.

The production department of Celltronics International wants to explore the relationship between the number of employees who assemble a subassembly and the number produced. As an experiment, two employees were assigned to assemble the subassemblies. They produced 15 during a one-hour period. Then four employees assembled them. They produced 25 during a one-hour period. The complete set of paired observations follows.   Number ofAssemblers   One-HourProduction (units)   2       15     4       25     1       10     5       40     3       30       The dependent variable is production; that is, it is assumed that different levels of production result from a different number of employees.         Click here for the Excel Data File     Draw a scatter diagram. On the graph below, use the point tool to plot the point corresponding to the first Number of Assemblers and her Production (No of Assemblers1). Repeat the process for the remainder of the sample (No of…

A private lake sells boating memberships and currently has 600 members. During the application process the potential members are asked which recreational activity they do the most. Their choices are fishing, skiing, boarding, swimming, or tubing. The lake manager chooses clients according to their interests to maximize the use of all areas of the lake. Every month, the lake rangers randomly sample the boats on the lake and categorize them according to the activity they are doing. The lake manager performs a chi-square goodness-of-fit test using the following null hypothesis to see whether their samples differ significantly from what the original applications claim. H0:pfish=0.26,pski=0.21,pboard=0.30,pswim=0.12,ptube=0.11 In order to meet the conditions for independence and large counts for a chi-square goodness-of-fit test, which of the following represents all possible sizes of the monthly samples?   n≥30 lowercase n is greater than or equal to 30 A 30≤n≤50 30 is less than…

StarHortons Cup, the coffee company, wants to determine how long caffeine lasts throughout the day when individuals have a cup of one of their 3 types of coffee at 9am. They will then measure the levels of caffeine in these individuals’ systems at 10am, 12am, 2pm, 4pm, 6pm and 8pm. They want to have at least 20 observations per group. How many separate/distinct groups of participants are needed if they want to conduct this experiment using a mixed-measures ANOVA?   18 6 20 3

A company was founded by two brothers in a certain city to provide in-home computer and electronic installation services as well as tech support to solve hardware, software, or computer peripheral crises. The company became highly successful with branches throughout the region and was purchased by a particular retail chain but continued to operate under its original name. A shipment of 28 processors was sent to the company. Twenty-one of them were defective. One of the company's technicians selected 5 of the processors to put in his parts inventory, and went on three service calls. Complete parts a through c below. ... a. Determine the probability that only 1 of the 5 processors is defective. The probability is 0.00748. (Round to five decimal places as needed.) b. Determine the probability that 3 of the 5 processors are not defective. The probability is (Round to five decimal places as needed.) ☆

An addictions researcher wants to see if male and female alcoholics differ in the type of alcohol they consume. She goes to a large alcohol detox facility, gets a sample of men and a sample of women, and checks each person's chart to find the beverage of choice. She classifies the beverages as (a) wine, (b) beer, or (c) hard liquor. She then figures out how many people of this sample of 66 people fall into each category. What type of test should she perform? Answer Choices: 2-way ANOVA   chi-square test of independence   correlation   chi-square goodness of fit   Imagine an elementary school teacher who is a follower of Carl Rogers and believes that unconditional positive regard leads to psychological health and positive behaviors. He obtains a random sample of 40 children from other teachers' classrooms at his school and, through home observation, he categorizes each child as receiving unconditional positive regard frequently, sometimes, or rarely. He then has each…
