Arrange the data into time periods width. Imprint the two portions "Selection" and "Repeat."

Foster a histogram of the data.

In the event that you some way or another figured out how to amass another lesser school, what bit of information would be more huge: the mode or the mean?

Determine the model mean.

Determine the model standard deviation.

Find the quartiles and foster a case plot

Is there any exemption?

Accept that you have a torn ACL ligament and are going up against an operation to fix it. The expert unveils the threats to you: Infection occurs in 1.7% of such errands, the support misfires in 13% of such exercises, and defilement and disillusionment both occur in 0.8% of such exercises.

Foster a Venn Diagram for the current condition.

What is the probability that the support misfires and there was no pollution?

If its understood that there was no tainting, what is the probability that the support succeeds?

advancing association did an investigation to find what kinds of pop (or "pop") people drink. Out of 85 people examined, they found that 59 drank cola, 43 drank root blend, and 45 drank lemon-lime. Of every single one of those outlined, 24 drank cola at this point not lemon-lime, 20 drank root brew but instead not cola, and 23 drank lemon-lime yet rather not root ale. 15 drank every one of the three sorts. Draw the Venn Diagram, by then answer these requests: a) what number people drank none of these three kinds of pop? b) what number people didn't drink cola? c) what number people drank root brew yet not lemon-lime? d) what number people drank both cola and lemon-lime yet not root ale? e) what number people drank simply root blend?

Question I [25] 1.1 A vehicle seller has set up that 40% of his potential customers slant toward single taxi vehicles while 60% blessing twofold taxi vehicles. From another investigation among his present clients, he got additional information which exhibits that 15% of clients who bought single taxi vehicles favor cooling while 65% of clients who bought twofold vehicles slant toward cooling. Required: a) What is the probability that a client who bought a singular taxi doesn't lean toward cooling? (5) b) What is the probability that a client slants toward a twofold taxi with cooling? (10) 1.2 It has been set up that realization of advancement exercises can be deferred considering shocking environment conditions. The probabilities are 0.6 that there will be unfavorable environment, and 0.85 that the advancement adventure will be done on time if the environment is acceptable and 0.35 that the improvement undertaking will be done on time if there is loathsome environment.

Problem 635 Consider a sound system with logic and singlehour listening reliability as given. Find the system reliability using the reliabilities given below.

A system consists ofjust one component which has a reliability of 0.95. The primary component has a baclrup component which has a reliability of 0.95 as shown below. If either the primary or baclrup component Functions, the system works. 1What is the reliability of this system? 2.

What would be the reliability of the system in Problem 1 if the switch reliability is 9.995? min Consider two systems, C and D. System C has three serial components each with reliabilities of 3.95. Two of the components have backups w'rth reliabilities of {1.90. System D has three serial components with reliabilities of [1.91]. Each of these components has a backup with a 0.91] reliability. If each DEED reliable component costs SlDDUJ each 0.95 component costs SZDDD, and the cost of failure is SlDD, what is the approximate cost of system C
