What is the useful life in hours for a product having a reliability of 0.985 and a failure rate of 0.015 failures per hour? A) 120 B) 200 C) 280 D) 360 E) 440
A firm had bought 15 machines with the price of RM 20000 per unit excluded the maintenance cost. Recently, these machines often suffer damage and this result in increasing the cost of repair and maintenance cost for each machine is RM10 per unit, while the repair cost is RM30 per unit. Table Q4 shows record that indicates this breakdown history on the machines.Frequency of Preventive Maintenance: 1 2 3 4 Probability of breakdown machine: 0.1 0.2 0.3 0.4 a.) The expected number...

Which of the following is NOT true about reliability? a) The "best" method for estimating reliability depends on a variety of situational factors b) Measures are either reliable or they're not c) The reliability of a measure cannot be directly asseses. It can only be estimated d) Reliabily coefficients can vary from 0.00 to 1.00
A system has three components with with reliability 0.6, 0.92 and 0.95, the system reliability is calculated as 1.01. how the components are arranged
The issues of validity and reliability are critical when evaluating your regression model. For reliability the most significant issues are serial correlation, heteroscedasticity and collinearity. What are these issues and how do they affect the reliability of our regression model? And how can we spot them if they are there?
Data Reliability: Evaluating data reliability is a critical part of the audit process. Explain the differences among the following in terms of reliability:: 1. Data from internal vs. external sources 2. Written data vs. verbal conversation records 3. Data obtained from direct vs. indirect methods 4. Data obtained from original documents versus electronic
