A company that makes language learning software wants to determine which of two approaches (Method A or Method B) to learning vocabulary would lead to the largest number of recalled words. The company wishes to evaluate the methods on 7 different languages (since languages differ in difficulty). Seven individuals, one per language, were recruited to learn words using Method A, and 7 individuals, one per language, were recruited to learn words using Method B.

After one month, each person completed a test of word recall. The data, representing the number of words recalled, are shown in the table below.

The company wishes to test whether there is a difference in the average number of words recalled between the two methods. Calculate the test statistic for this hypothesis to two decimal places. Take all calculations toward the final answer to three (3) decimal places.

PEZ Candy Inc. produces the popular small candy that is dispensed in collectible flip-top dispensers. PEZ candy was invented as a breath mint in Vienna, Austria, in 1927. The name PEZ is derived from “pfefferminz” which is the word for peppermint in German.

In the United States, PEZ candies are produced in a factory in Connecticut since 1973. The PEZ candies are made from about 95% sugar, which makes the PEZ product cost particularly sensitive to changes in the cost of sugar. The cost of sugar in the United States has been significantly increasing over the past year, due in least at part, to preliminary tariffs imposed by the U.S. government on Mexican sugar. In addition, the cost of labor has been increasing due to increases in the minimum wage in the U.S. For these reasons, PEZ expects to raise its prices in 2015.

If the related cost standard is not adjusted, what variance(s) will be impacted by the rising cost of labor? What department would typically be responsible for explaining this variance(s)? (paragraph form)

Imagine you are the manager of a non-profit business, and you are looking to hire a recent college graduate. You list the position as paying $20,000/year. After interviewing candidates you decide that some will be offered the expected salary, while some will be offered more because of experience and interviewing skills. Others will be offered less than expected until they can demonstrate competence and their salary will increase when they are fully qualified.

Using Microsoft^® Excel^®, run a chi square Goodness of Fit test to determine whether these observed starting salaries are significantly different. What do the findings tell you?

Write a 75- to 100-word summary to describe your results.

Paste your Microsoft^® Excel^® output below your summary.

The following is a small data set of 25 observations. I want you to calculate some statistics by hand to cement the class material. You can use the regular formula for the variance or the computational formula - I’m just interested in the correct result. If you use the computational formula, you will want to calculate a separate row of each value squared in order to calculate the Sum(x^2). Excel can be used to solve this problem.

1. Create a Stem and Leaf Plot of the data (it is easy to do in Word by making a two column table and entering the numbers in there, bolding the stems)

b. Calculate the following (show your work):

• Mean
  • Median
  • Mode
  • Range
  • Variance
  • Std. Deviation
  • Coefficient of Variation

c. Calculate a z-score for a data value of 46. Describe this in words.

At the end of the lab, you will be asked to respond to the following in a 2- to 2.5-page response at the end of your Microsoft Word document:

Explain the types of information that can be stored in an Active Directory user record.

Address the following in your response:

• What are some of the additional tabs that are available in the Active Directory Users and Computers "Advanced Features" mode?
• What are some of the specific challenges and risks associated with accountmanagement in a large infrastructure?
• How can inadequate access controls or access management leave critical information vulnerable?
• What protections does encryption offer and how important is key management tokeeping any encryption system secured?
• Considera cloud-hosted Infrastructure as a Service (IaaS) environment with many users accessing these systems from all over the world. What advantages or challenges might there be managing these identities and associated keys?

Finally, conclude this week's assignment with a page explaining how the tools and processes demonstrated in the lab might be used by an infrastructure administrator to help secure an environment.

Question 1 In our lectures, we have discussed different insights of understanding the distinction between fintech and financial innovation. Briefly discuss the difference between fintech and financial innovation using your own words. (Max. 250 words) You are required to use an academic referencing convention. The word count does not include citations.

Question 2 Name the different banks and NBFCs in the Saudi market. List four different innovations that are incorporated in some of these institutes that have disrupted previous services.

Question 3 is an opportunity to explore and refine an idea or area that is of interest to you. Address the following points in your answer: • What is the innovation, technology, or sector you believe is most interesting in financial services? • What are the reasons why you think the context of your choice has the potential to be disrupted by your idea? • What are the potential implications of this new idea within your context? • Justify your response with your own opinion as well as research.

Guided Assignment Problem 1: Multiplication

Review the Three-Question Approach used to verify the Factorial recursive algorithm in Ch. 3.2.

Your Tasks:

1. Now we need to develop a recursive algorithm for multiplication operation with two positive integers without using the multiplication operator. Your answer should be in pseudocode or Java code format.
2. Then use the Three-Question Approach to verify your recursive algorithm. No coding is required for this assignment.

   Recursive method header given as: int multiplication (int a, int b)

   Hints

3. a multiply b is to the same is b + (a -1) multiply b, in terms of recursion, the problem is simplified. The process keeps going until base case is reached, which is 1*b = b.
4. randerson112358. (2015, Feburuary 13). Recursion function to multiply two positive integers. [Video file, Length 5:13].

Scenario # 2 Your facility is a large children’s hospital in north Texas. Until recently your facility was part of a larger health care facility run by the state. The facility is now corporately owned and operated. During this reorganization period a major fire occurred at a local elementary school. Over 100 injured children were sent to your facility for care. You encountered many problems: care was delayed and inappropriate for many children because of the nature of their injuries due to lack of parental consent for treatment and smoke inhalation and burns. Your task is to develop a disaster plan specifically to address the deficiencies and to reshape your public image following the fire at the elementary school.
