A microwave manufacturing company has just switched to a new automated production system. Unfortunately, the new machinery has been frequently failing and requiring repairs and service. The company has been able to provide its customers with a completion time of 6 days or less. To analyze whether the completion time has increased, the production manager took a sample of 36 jobs and found that the sample mean completion time was 6.5 days with a sample standard deviation of 1.5 days. a) At a significance level of 0.10, test whether the completion time has increased. b) Find and interpret a 99% confidence interval for the mean completion time.

Oceanside marine company manufactures special metallic materials and decorative fittings for luxury yachts that require highly skilled labor. oceanside uses standard costs to prepare its flexible budget. for the first quarter of the year, direct materials and direct labor standards for one of their popular products were as follows: direct materials: 2 pound per unit; $ 11 per pound direct labor: 2 hours per unit; $ 19 per hour oceanside produced 2 comma 000 units during the quarter. at the end of the quarter, an examination of the direct materials records showed that the company used 7 comma 500 pounds of direct materials and actual total materials costs were $ 98 comma 100. what is the direct materials cost variance? (round any intermediate calculations to the nearest cent, and your final answer to the nearest dollar.)

The cutting department of cassel company has the following production and cost data for july. production costs 1. transferred out 12,300 units. beginning work in process $0 2. started 3,900 units that are 60% materials 62,856 complete as to conversion labor 12,622 costs and 100% complete as manufacturing overhead 23,100 to materials at july 31. materials are entered at the beginning of the process. conversion costs are incurred uniformly during the process. determine the equivalent units of production for (1) materials and (2) conversion costs. materials conversion costs total equivalent units of production link to text link to text compute unit costs. (round unit costs to 2 decimal places, e.g. 2.25.) materials $ conversion costs $ link to text link to text prepare a cost reconciliation schedule. (round unit costs to 2 decimal places, e.g. 2.25 and final answers to 0 decimal places, e.g. 1,225.) cost reconciliation costs accounted for transferred out $ work in process, july 31 materials $ conversion costs total costs $

Henry crouch's law office has traditionally ordered ink refills 55 units at a time. the firm estimates that carrying cost is 35% of the $11 unit cost and that annual demand is about 240 units per year. the assumptions of the basic eoq model are thought to apply. for what value of ordering cost would its action be optimal? a) for what value of ordering cost would its action be optimal?
