Race One Motors is an Indonesian car manufacturer. At its largest manufacturing facility, in Jakarta, the company produces subcomponents at a rate of 300 per day, and it uses these subcom-ponents at a rate of 12 500 per year (of 250 working days). Holding costs are $2 per item per year, and ordering costs are $30 per order. a) What is the economic production quantity? b) How many production runs per year will be made? c) What will be the maximum inventory level? d) What percentage of time will the facility be producing components? e) What is the annual cost of ordering and holding inventory?

The data in Table B represents the times (in seconds) for men of three different ages (40, 50 and 60) in each of three different fitness classes (1, 2 and 3) to run a 2 km course. For each runner, age is recorded in the first column, fitness category is recorded in the second column, and running time is recorded in the third.

            Two men in each of the nine categories ran the course. You should be interested in determining whether age and/or fitness affect running time. Each data point can be classified according to age of the runner or according to fitness of the runner. The data therefore requires a two‑way analysis of variance. It is possible that differences among ages of runner will depend upon the fitness categories of those two runners. The model for the analysis should include an interaction term.

                                                                        NOTE

In analysis of variance, the null hypothesis should be rejected whenever the calculated F‑statistic is greater than the critical value for a chosen significance level and appropriate numerator and denominator degrees of freedom. Equivalently, the null hypothesis should be rejected whenever the computed p‑value is less than the chosen significance level. Use α = 0.01 (significance level =1 %) and answer the following two questions.

n Prepare a table of mean running times and answer the following three questions.

Todd is a 44-year-old electrical engineer who works 50–60 hours per week. He is 5’9”, 233 pounds, with total cholesterol of 192 mg · dL–1, low-density lipoprotein (LDL) of 138 mg · dL–1, high-density lipoprotein (HDL) of 41 mg · dL–1, triglycerides of 200 mg · dL and blood glucose of 120 mg dL. Todd’s resting heart rate is 81 bpm and blood pressure is 144/86 mmHg. His waist and hip circumference measures are 42 inches and 40 inches, respectively.

Todd has never smoked, but usually has one to two glasses of wine with dinner. He reports no leisure-time physical activity and does not exercise on a regular basis (less than two sessions per month).

Todd denies all complaints of chest discomfort and shortness of breath at rest or with exertion; however, he has gained 20 pounds over the last 2 years. Todd’s wife reports he snores frequently and has difficulty waking up in the mornings. Further testing reveals that Todd has obstructive sleep apnea and is being treated with continuous positive airway pressure (CPAP).

A review of his family history reveals that Todd’s father had double-bypass surgery at age 53 and suffered a fatal myocardial infarction at age 62. Todd’s brother (42 years old) also is hypertensive and was recently diagnosed with type 2 diabetes, which is being treated with diet and physical activity recommendations.

Questions:

Known CV, metabolic or renal disease?

Absolute or relative contraindications to exercise testing?

Signs or symptoms suggestive of disease?

Moderate or vigorous intensity? Why?

Medical clearance needed? Why or why not?

Should they get medical clearance before progressing to higher intensities? Why or why not?

ACSM CVD Risk Factors? How many?

In a survey, 32 people were asked how much they spent on their child's last birthday gift. The results were roughly bell-shaped with a mean of $50 and standard deviation of $8. Construct a confidence interval at a 80% confidence level.

Design a clock display to show the time in hours, minutes, and seconds. Assume that we have a clock of exactly 1 KHz (1000 clock pulses per second). It will use 6 seven-segment displays and operate either in military time (hours 00 to 23) or regular time (1 to 12, with AM and PM). An input line, x, differentiates between the two. A seventh display is used to show A or P in the latter case; it is blank otherwise. Assume that there is a BCD-to-seven-segment decoder driver available; one is needed for each display other than the AM /PM one.

Optimal Capital Structure with Hamada

Beckman Engineering and Associates (BEA) is considering a change in its capital structure. BEA currently has $20 million in debt carrying a rate of 7%, and its stock price is $40 per share with 2 million shares outstanding. BEA is a zero growth firm and pays out all of its earnings as dividends. The firm's EBIT is $13.523 million, and it faces a 40% federal-plus-state tax rate. The market risk premium is 6%, and the risk-free rate is 5%. BEA is considering increasing its debt level to a capital structure with 50% debt, based on market values, and repurchasing shares with the extra money that it borrows. BEA will have to retire the old debt in order to issue new debt, and the rate on the new debt will be 14%. BEA has a beta of 1.2.

What is the total value of the firm with 50% debt? Enter your answers in millions. For example, an answer of $10,550,000 should be entered as 10.55. Do not round intermediate calculations. Round your answer to three decimal places.

Seasonal affective disorder (SAD) is a type of depression during seasons with less daylight (e.g., winter months). One therapy for SAD is phototherapy, which is increased exposure to light used to improve mood. A researcher tests this therapy by exposing a sample of patients with SAD to different intensities of light (low, medium, high) in a light box, either in the morning or at night (these are the times thought to be most effective for light therapy). All participants rated their mood following this therapy on a scale from 1 (poor mood) to 9 (improved mood). The hypothetical results are given in the following table.

(a) Complete the F-table and make a decision to retain or reject the null hypothesis for each hypothesis test. (Round your answers to two decimal places. Assume experimentwise alpha equal to 0.05.)

State the decision for the main effect of the time of day.

Retain the null hypothesis.

Reject the null hypothesis.    

State the decision for the main effect of intensity.

Stock Inc. has two sites in Pittsburgh that are four miles apart. Each site consists of a large factory with office space for 25 users at the front of the factory and up to 50 workstations in two work cells on each factory floor. All office users need access to an inventory database that runs on a server at the Allegheny Street location; they also need access to a billing application with data residing on a server at the Monongahela site. All factory floor users also need access to the inventory database at the Allegheny Street location. Office space is permanently configured, but the manufacturing space must be reconfigured before each new manufacturing run begins. Wiring closets are available in the office space. Nothing but a concrete floor and overhead girders stay the same in the work cell areas. The computers must share sensitive data and control access to files. Aside from the two databases, which run on the two servers, office computers must run standard word-processing and spreadsheet programs. Work cell machines are used strictly for updating inventory and quality control information for the Allegheny Street inventory database. Workstations in the manufacturing cells are switched on only when they’re in use, which might occur during different phases of a manufacturing run. Seldom is a machine in use constantly on the factory floor. Use the following write-on lines to evaluate the requirements for this network. After you finish, determine the best network topology or topology combination for the company. On a blank piece of paper, sketch the network design you think best suits ENorm, Inc.’s needs.

● Will the network be peer to peer or server-based?

● How many computers will be attached to the network?

● What topology works best for the offices, given the availability of wiring closets? What topology works best for the factory floor, given its need for constant reconfiguration?

can i also have the network design please
