Suppose a system consists of four components, con-nected in parallel, having the reliabilities 0.8, 0.7, 0.7, and 0.65, respectively. Find the system reliability.

A system has five components connected as shown in the diagram. Assume A, B, C, D, and E function independently. If the probabilities that A, B, C, D, and E function 0.50, 0.65, 0.75, 0.95, and 0.80 respectively, what is the probability that the system fails?

A production line has three machines A, B, and C, with reliabilities of .90, .95, and .92, respectively. The machines are arranged so that if one breaks down, the others must shut down. Engineers are weighing two alternative designs for increasing the line's reliability. Plan 1 involves adding an identical backup line, and plan 2 involves providing a backup for each machine. In either case, three machines (A, B, and C) would be used with reliabilities equal to the original three. a. Compute overall system reliability under Plan 1. (Round your intermediate calculations and final answer to 4 decimal places.) Reliability b. Compute overall system reliability under Plan 2. (Round your intermediate calculations and final answer to 4 decimal places.) Reliability

During the get-together for Gerdau developers, 17 employees sat around a large round table. Each of the collaborators received a paper that said if he should say only the truth or only a lie. During the dynamic performed, each one should say which colleagues were lying and which were telling the truth. At the end of the game, all employees who were participating said: "The two people next to me are liars". At a minimum, how many employees received the paper saying to tell only the truth?

Valve A: 92% Valve B: 94% Valve C: 93%

I conduct an online study to determine whether rewards reduce procrastination. All participants are asked to complete a task sometime before a deadline (10 days from now). The computer randomly assigns participants to one of three groups, and emails them their instructions; one group receives a reward as soon as they do the task (contingent reward); a second group receives rewards as soon as they finish the task as long as it is before the deadline (non-contingent reward) and the third group does not receive rewards at all (no reward). Three participants in the no reward condition do not complete the task, and so are dropped from analyses. The dependent variable is the amount of time (in days) it takes participants to complete the task. The JAMOVI output is attached. Post-hoc Tukey tests show that...

A production line has three machines A, B, and C, with reliabilities of .90, .95, and .98, respectively. The machines are arranged so that if one breaks down, the others must shut down.

In either case, three machines (A, B, and C) would be used with reliabilities equal to the original three. a. Compute overall system reliability under Plan 1.
