We want to make a machine that detects an alternating pattern. It should indicate whether

three or more alternating bits have been observed on our serial input X. So, if X has 010 or

101, the output Z will be high, otherwise the output will be low. Assume that when the

machine starts up or is reset, is has not seen any bits of data to work with and the output

cannot go high until it sees the third bit of data.

Your task is to design two CONCEPTUALLY different synchronous state machines (Mealy

and Moore) in Logisim. You can use either J-K or D flip-flops.

Your Task:

Make the State Diagram

Make the State Assignments

Make the State Transition Table

Make the K-Maps

Derive the Equations

Implement in Logisim

Q38 Answer the following questions about variability of data sets: [4 Marks]

(a) What is the primary disadvantage of using the range to compare the variability of data sets?

(b) Describe the sample variance using words rather than a formula. Do the same with the population variance.

(c) Can the variance of a data set ever be negative? Explain.

(d) Can the variance ever be smaller than the standard deviation? Explain.

Evaluate the role of Mental Health Counselor, beginning with your own description of the field itself, including both the history and the philosophies involved, explaining where your specialization fits, and describing how your specialization might collaborate with an Addictions Counselor. Cite the articles or other sources you use for the basis of your ideas.

In this part, specifically address the following questions:

1) How would you describe the key philosophies of the counseling profession: wellness, resilience, and prevention? Choose a wellness model, and explain how that model impacts the way in which counselors view clients and the concerns brought to counseling, including the kinds of information counselors need to have about their clients.

Task 1: Roulette wheel simulation

A roulette wheel has 38 slots of which 18 are red, 18 are black, and 2 are green. If a ball spun on to the wheel stops on the color a player bets, the player wins. Consider a player betting on red. Winning streaks follow a Geometric(p = 20/38) distribution in which we look for the number of red spins in a row until the first black or green. Use the derivation of the Geometric distribution from the Bernoulli distribution to simulate the game. Namely, generate Bernoulli(p = 20/38) random variates (0 = red; 1 = black or green) until a black or green occurs.

Code set-up

A while loop allows us to count the number of spins until a loss. If we use indicator variable lose to note a win (1) or loss (0), the syntax is “while we have not lost (i.e., lose==0), keep spinning.” Once you win, the while loop ends and the variable streak has counted the number of spins. Try running a few times.

streak = 0
lose = 0
p = 20/38
while(lose==0){
lose = (runif(1) < p) # generate Bernoulli with probability p
streak = streak + 1 # tally streak
}
streak

The problem

The code chunk above performs the experiment once: spin the roulette wheel until you lose and record the number of spins. Simulate 1000 experiments. As usual, do this by wrapping the code chunk above within a for-loop and storing the number of spins streak in a vector.

Report the following:

• Histogram of the win streak length. Note that this is a discrete distribution so should place histogram bars at discrete values {0, 1, 2, …}. This may be done with the breaks option within hist. If your storage variable is called winstreak:

hist(winstreak, br=seq(min(winstreak)-0.5, max(winstreak+0.5)), main="")

• Average length of the win streak. [Answer here]
• Standard deviation of the winning streak lengths. [Answer here]
• Compare the empirical average and standard deviation in the previous two bullets to the true values from the Geometric(p = 20/38) distribution.

• Longest winning streak. [Answer here]

A random sample of 100 observations from a quantitative population produced a sample mean of 29.8 and a sample standard deviation of 7.2. Use the p-value approach to determine whether the population mean is different from 31. Explain your conclusions. (Use α = 0.05.)

State the null and alternative hypotheses. (Choose Correct Letter)

(a) H₀: μ = 31 versus H_a: μ < 31

(b) H₀: μ ≠ 31 versus H_a: μ = 31    

(c) H₀: μ < 31 versus H_a: μ > 31

(d) H₀: μ = 31 versus H_a: μ > 31

(e) H₀: μ = 31 versus H_a: μ ≠ 31

Find the test statistic and the p-value. (Round your test statistic to two decimal places and your p-value to four decimal places.)

State your conclusion. (Choose Correct Letter)

(a) The p-value is greater than alpha, so H₀ is not rejected. There is sufficient evidence to indicate that the mean is different from 31.

(b) The p-value is less than alpha, so H₀ is rejected. There is insufficient evidence to indicate that the mean is different from 31.    

(c) The p-value is greater than alpha, so H₀ is not rejected. There is insufficient evidence to indicate that the mean is different from 31.

(d) The p-value is less than alpha, so H₀ is rejected. There is sufficient evidence to indicate that the mean is different from 31.

According to Max Weber's definition of a state/sovereign i.e. "Something is a state/sovereignty if and insofar as its administrative staff successfully upholds a claim on the monopoly of the legitimate use of violence in the enforcement of its order" Would you argue that the United Nations is considered a state? what aspects of the UN would you argue don't fit Weber's framework and which do?

1. Develop the contingency planning policy.
2. Conduct the business impact analysis (BIA).
3. Identify preventive controls.
4. Create contingency strategies.
5. Develop an Information System Contingency Plan.
6. Ensure plan testing, training, and exercises.
7. Ensure plan maintenance.

In 500-750 words, create a sentence outline of an Information System Contingency Plan (ISCP) for your organisation or an organisation you are familiar with, based on the seven steps listed above and described in the NIST 800-34 directive. Your sentence outline should briefly describe each topic of the ISCP. Each sentence, instead of simply identifying the ISCP topic, should be a brief statement about that topic. Each sentence should express the idea that that section of the plan will cover as part of describing the overall ISCP.

Please research and review the Affordable Care Act and Patient Protection Act. Upon completion of your research and review, provide an analysis: What is the key element of each Act? Provide a complete and detailed description of the key elements. Provide the section of the Act the key elements is located in.

Using linked lists, write a Python program that performs the following tasks:

• store the records for each college found in the input file - colleges.csv - into a linked list. (File includes name and state data fields)
• allow the user to search the linked list for a college’s name; display a message indicating whether or not the college’s name was in the database
• allow the user to enter a state's name and display (to the screen) the total count of colleges in that state

If you use the Node and Linked List class definitions from the zyBook, please make sure you cite this reference in your comments.(dont use if not needed but if you need to use this I will reference them myself)
