1. A credit card watchdog group claims that there is a difference in the mean credit card debts of households in California and Illinois. The results of a random survey of 250 households from each state are shown at the left. The two samples are independent. Assume that s1 = $1045 for Californiaand s2 = $1350 for Illinois. Do the results support the group’s claim? Use a = 0.05.2. A survey indicates that the mean annual wages for forensic science technicians working for local and state governments are $55,950 and $51,100, respectively. The survey includes a randomly selected sample of size 100 from each government branch. Assume that the population standard deviations are $6200 (local) and $5575 (state). The two samples are independent. At a = 0.10, is there enough evidence to conclude that there is a difference in the mean annual wages?a. Identify the claim and state H0 and Ha.b. Identify the level of significance a.c. Find the critical values and identify the rejection regions.d. Find the standardized test statistic z. Sketch a graph.e. Decide whether to reject the null hypothesis.f. Interpret the decision in the context of the original claim.
In Zen Buddhism there is a familiar koan, or riddle, that says, “Last night I dreamt I was a butterfly. How do I know today that I am not a butterfly dreaming I am a man?” How can you relate this to the idea that we construct a version of reality out of the more basic world of physical energies surrounding us.
Article ReviewsYou will write a 3 page review/abstract/summary on an article from a peer-reviewed scholarly journal. This is to assess your ability to select and summarize the research of others, analyze and apply the research of others, and communicate professionally and effectively to their regard.

After completing the reading this week, please review table 1.2 in the text and review the distinction between leadership and management. Then think about this in regard to how senior leaders versus senior managers lead change in an organization (especially when it comes to technical change in an organization).This week please reflect on these concepts and answer the following questions:When implementing change in an organization, there are always culture issues that are faced, such as not accepting change, determine how differently this would be handled thinking about the management versus leadership constructs?When dealing with performing work, how is this implemented differently within the management versus leadership constructs?Please be sure to answer all of the questions above in the initial post.Please ensure the initial post and two response posts are substantive. Substantive posts will do at least TWO of the following:Ask an interesting, thoughtful question pertaining to the topicExpand on the topic, by adding additional thoughtful informationAnswer a question posted by another student in detailShare an applicable personal experienceProvide an outside sourceMake an argumentAt least one scholarly (peer-reviewed) resource should be used in the initial discussion thread. Please ensure to use information from your readings and other sources from the UC Library. Use APA references and in-text citations.
Before we encounter sources engaged in the discourse of resilience, it would be a good idea to reflect on what resilience means to you.Without consulting outside sources, define resilience in your own words. What words and traits do you associate with the term? How do we know resilience when we see it? Who or what can be resilient? In which contexts do we use the term? You can also pose questions about resilience here. The idea is for us to start a conversation about the term and take stock of what we know and how we feel about resilience before we engage with outside sources.
Explain the advantages of using Layers of Protection Analysis (LOPA). What are the potential disadvantages? What would you say to a co-worker or supervisor who complains that LOPA is unnecessary because different organizations/industries already have risk management analysis methods?

There are three standardized approaches to digital signatures: RSAPSS, ECDSA, and the original DSA developed by NIST. One advantage of RSA-PSS is that RSA-based signature schemes are already widely used in commercial applications. One advantage of DSA is that it is the original scheme approved by NIST and is implemented in numerous packages, especially within the US government and government contractors. One advantage of ECDSA is efficiency.Discuss the relative merits of the three approaches for a new commercial product.
What Should I Say?”SynopsisThe sudden heart attack of his predecessor, Bill Andrews, propelled Russell Hart into a temporary top management assignment for Kresk International in the company’s new Middle East Division in Riyadh, Saudi Arabia. After six months, Russell went to Dallas to report at the semiannual board meeting. The board would determine if he or Bill Andrews would have the permanent assignment at the end of the year. Russell enjoyed the company’s top assignment and hoped to impress management at the meeting so that he would be named director of the Middle East Division. In Dallas, Russell has an impromptu chat with his assistant Christopher Dunn where he describes in depth the atrocious behavior of a colleague, Youssef Said. Russell has observed how Said’s behavior has made a few employees resign. He also mentions how Said loves to humiliate employees and how his total disregard for the opinion of others appalls Russell. Russell adds that Said has an inner circle or “family” whom he favors. He always seems to work deals and bend rules. Russell feels Youssef Said’s methods may not be in the best interest of the company. He wants the board to notice this and asks Christopher for advice because the board, at this point of time, seems to be impressed by Youssef Said.Questions:What do you think Russell Hart should include in his report about Youssef Said? Why? What would you do in his position?What amount or kind of courage will be required for Hart to disclose everything honestly? How would you advise Hart to acquire that courage?At which stage of Kohlberg’s moral development scale would you place Youssef Said, Russell Hart, and Bill Andrews? Why?
