- Data was collected for 40 randomly selected trees growing in the median strip of a busy freeway. The height of each tree (in inches) was recorded. Data was recorded to the nearest whole inch. The data is summarized in the histogram below. Based on this histogram, determing the minimum and maximum possible tree heights for the recorded data. Note: Each class contains its lower class boundary, but not its upper class boundary.Minimum tree height = inchesMaximum tree height = inchesa) Final marks in Maria's Data Management class are based on 70% for term work, 15% for theexam, and 15% for the final course project. What term mark did Maria receive if her final markwas 90 and she received 85 on the exam and 97 on her final project? Show all working out. b)In a study, the effects of the mane of a male lion as a signal of quality to mates and rivals was explored. Four life-sized dummies of male lions provided a tool for testing female response to the unfamiliar lions whose manes varied by length (long or short) and color (blonde or dark). The female lions were observed to see whether they approached each of the four life-sized dummies. Complete parts (a) through (e) below. a. Identify the experimental units. Choose the correct answer below. The female lions The male dummies The mane colors The mane lengths Part 2 b. Identify the response variable. Choose the correct answer below. A.

- The service charge for repairs at an automobile service center is based on a standard time specified for each type of repair. The time specified for the replacement of the universal joint a driveshaft is one hour. To better serve the customers, the management would like to change the time specified in their service fee rates. The manager reviews such repairs and assumed that the workers are working faster than the standard time. The manager observed 30 of such repairs and gets an average repair time of 0.86 hours with a standard deviation of 0.32 hours. Test at the 1% level of significance the null hypothesis for the actual average time for this repair. Show the following steps. a. Formulation of the hypothesis and identifying the claimb. Determining what test to be usedc. Identifying the significance level and critical valued. Computation of the test statistice. Comparing the absolute value of the computed test statictic and critical value, decide whether null hypothesis is accepter…Researchers created two test sheets, each sheet showing 2020photos of the faces of dog‑owner pairs. The two sheets were equivalent with respect to breed, diversity of appearance, and gender of owners. On the first sheet the dogs were matched with their owners, while on the second sheet the dogs and owners were deliberately mismatched. Three experiments were conducted, and in all experiments, subjects were asked to "choose the set of dog‑owner pairs that resemble each other, Sheet 11or Sheet 22," and were simply told the aim of the research was a "survey on dog‑owner relationships." In the first experiment, the original sheets were shown to subjects; in the second experiment, just the mouth region of the owners was blacked out in all the pictures on both sheets; while in the third experiment, just the "eye region" of the owners was blacked out. Subjects were assigned at random to the three experimental groups, and in each experiment, the number of subjects who selected the sheet with…When MapReduce is executed, data are first divided up into manageable subsets and distributed to different computers for storing and processing. Then, the answers from each of those computers are combined into one answer. Notice that the first sentence clarifies that processing (and storing) is done by "different computers." The second sentence mentions these different computers again, this time referring to them as "those computers". What term is often used to refer to each one of those different individual computers? (hint: The general term is often followed by a number as a means of identifying specific computers in the programming model.) Cluster Processor O Client O Node
- A manufacturer produces washdown motors for the food service industry. The company manufactures the motors to order by modifying a base model to meet the specifications requested by the customer. The motors are produced in a batch environment, with the batch size equal to the number ordered. The manufacturer has recently sampled 50 customer orders. The motor manufacturer would like to determine if there is a relationship between the cost of producing the order and the order size so that it could estimate the cost of producing a particular size order. (A) Use the sample data to estimate the least squares regression model. (B) Provide an interpretation of the regression coefficients. (C) Test the significance of the overall regression model using a significance level of 0.02. (D) The company has just received an order for 30 motors. Use the regression model developed in part a to estimate the cost of producing this particular order. (E) Referring to part d, what is the 95% confidence…A camera shop stocks eight different types of batteries, one of which is type A76. Assume there are at least 32 batteries of each type.

It follows that the number of ways the total inventory can be distributed is (b) How many ways can a total inventory of 32 batteries be distributed among the eight different types if the inventory must include at least four A76 batteries? (c) How many ways can a total inventory of 32 batteries be distributed among the eight different types if the inventory includes at most three A76 batteries?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 continuous timing method in direct time study was used to obtain the element timesfor a worker-machine task as indicated in the table below. Element c is a machine-controlledelement and the time is constant. Elements a, b, d, e, and f are operator-controlled andexternal to the machine cycle, and they were performance rated at 80%. If the machineallowance is 25%, and the worker PFD allowance is 15%, determine (a) the normal time,(b) the standard time for the cycle, and (c) the worker’s efficiency if the worker completes360 work units working 7.2 hr on an 8-hour shift.1. A computer manager interested to know how efficiency of his/her new computer program which depends on the size of incoming data. Efficiency will be measured by the number of processed requests per hour. In general, larger data sets require more computer time, and therefore, fewer requests are processed within 1 hour. Applying the program to data sets of different sizes, the following data were gathered. Data size (gigabytes) Processed requests 40 a) Determine the association between data size and processed requests and interpret its meaning. b) Fit a regression equation to predict the efficiency of a new computer for data size 12 gigabytes 6. 7 7 8 10 10 15 55 50 41 17 26 16A national truck rental services has a surplus of one truck in each of the cities, 1, 2, 3, 4, 5, and 6 and a deficit of one truck in each of the cities 7,8,9,10,11 and 12.The distance (in kilometers) between the cities with a surplus and cities with deficit are displayed below:a) How should the trucks be displayed so as to minimize the total distance travelled? 1 2 3 4 5 6 7 41 72 39 52 25 51 8 22 29 49 65 81 50 9 27 39 60 51 32 32 10 45 50 48 52 37 43 11 82 40 40 60 51 30
