Question

100%

The performance of a computer is observed over a period of 2 years
(52 weeks/year) to check the claim that the probability is 0.20 that its downtime will exceed
5 hours in any given week. Testing the null hypothesis p = 0.20 against the alternative
hypothesis p 6= 0.20, what can we conclude at the level of significance α = 0.05, if there were
only 11 weeks in which the downtime of the computer exceeded 5 hours?

Consider a maximization problem that is being solved by Simulated Annealing. Let the objective function value of the current state, s, be 1000. Let this state have 5 successors/neighbors: s1(950), s2(975), s3(1000), s4(1000), and s5(1050). The numbers in parentheses represent the corresponding objective function values. The current temperature is 100. The probability that the next state is: 1. s1 = [Select] 2. s2 = [Select] 3. s3 [Select] = 4. s4= [Select] [Select] 5. s5 0.778 0.121 0.156 0.2 0.606
For the Covid-19 pandemic, let’s make the following assumptions: (i) the natural infection rate is 20% (i.e., a person who is not vaccinated has 20% chance of being infected); (ii) the vaccine is 90% effective at preventing Covid-19 infection (i.e., a vaccinated person has only 2% chance of being infected); (iii) the probability of a random person being vaccinated is 60%. Without knowing whether or not a person is vaccinated, what is the probability that this person will be infected? Given that a person is infected, what is the conditional probability that this person is vaccinated?
Students graduating Atlantis University are being administered a test to check their general competence level at the end of the study program. From a random sample of 100 students, 95 passed and 5 failed. We aim to construct a 95% confidence interval for the proportion p of students at Atlantis University who have achieved a satisfactory competence level after their studies. Answer the following questions: (a) The critical z-value for this problem (the z-value to be used) is z = (give the exact value to TWO decimal places N.xx) (b)The middle of the interval is %. (ROUND to the nearest integer) (c) The error margin is % (use one decimal only and give in terms of percentages).
Correct answer will be upvoted else downvoted. Computer science. In the event that right now Pekora hops on trampoline I, the trampoline will dispatch her to situate i+Si, and Si will become equivalent to max(Si−1,1). At the end of the day, Si will diminish by 1, besides of the case Si=1, when Si will stay equivalent to 1. On the off chance that there is no trampoline in position i+Si, this ignore is. Any other way, Pekora will proceed with the pass by hopping from the trampoline at position i+Si by a similar principle as above. Pekora can't quit hopping during the pass until she arrives at the position bigger than n (in which there is no trampoline). Poor Pekora! Pekora is an underhanded hare and needs to demolish the jumping place by diminishing all Si to 1. What is the base number of passes she really wants to diminish all Si to 1? Input The main line contains a solitary integer t (1≤t≤500) — the number of experiments. The principal line of each experiment…
