Q3. loral corporation manufactures parts for an aircraft company. it uses a computerized numerical controlled (cnc) machining center to produce a specific part that has a design (nominal) target of 1.275 inches with tolerances of ± 0.020 inch. the cnc process that manufactures these parts has a mean of 1.285 inches and a standard deviation of 0.005 inch. compute the process capability ratio and process capability index, and comment on the overall capability of the process to meet the design specifications.

White company has two departments, cutting and finishing. the company uses a job-order costing system and computes a predetermined overhead rate in each department. the cutting department bases its rate on machine-hours, and the finishing department bases its rate on direct labor-hours. at the beginning of the year, the company made the following estimates: department cutting finishing direct labor-hours 6,000 30,000 machine-hours 48,000 5,000 total fixed manufacturing overhead cost $ 264,000 $ 366,000 variable manufacturing overhead per machine-hour $ 2.00 " variable manufacturing overhead per direct labor-hour " $ 4.00 required: 1. compute the predetermined overhead rate for each department. 2. the job cost sheet for job 203, which was started and completed during the year, showed the following: department cutting finishing direct labor-hours 6 20 machine-hours 80 4 direct materials $ 500 $ 310 direct labor cost $ 108 $ 360 using the predetermined overhead rates that you computed in requirement (1), compute the total manufacturing cost assigned to job 203. 3. would you expect substantially different amounts of overhead cost to be assigned to some jobs if the company used a plantwide predetermined overhead rate based on direct labor-hours, rather than using departmental rates?

Guardian inc. is trying to develop an asset-financing plan. the firm has $450,000 in temporary current assets and $350,000 in permanent current assets. guardian also has $550,000 in fixed assets. assume a tax rate of 40 percent. a. construct two alternative financing plans for guardian. one of the plans should be conservative, with 70 percent of assets financed by long-term sources, and the other should be aggressive, with only 56.25 percent of assets financed by long-term sources. the current interest rate is 12 percent on long-term funds and 7 percent on short-term financing. compute the annual interest payments under each plan.

Bond j has a coupon rate of 6 percent and bond k has a coupon rate of 12 percent. both bonds have 14 years to maturity, make semiannual payments, and have a ytm of 9 percent. a. if interest rates suddenly rise by 2 percent, what is the percentage price change of these bonds?
