When performing Risk Analysis as part of the task Analyse Risk (which is part of the Strategy Analysis knowledge area of the Business Analysis Body of Knowledge), we may develop a risk register as a table of entries for each identified risk.

For each identified risk we make a judgement about probability as being either low, medium or high. We also make a judgement about impact as being either low, medium, or high. These contribute to making a final judgement about the risk’s risk level as being either low, medium or high.

a) Explain the difference between probability of a risk and impact of a risk, and then describe what the difference between low and high judgement levels mean for these aspects of risk.

b) If a particular risk has been judged to have low probability but high impact, what might its final risk level be judged as?

c) If another particular risk has been judged to have high probability but low impact, what might its final risk level be judged as?

I would like to have a response on this forms or post for my psychology class. The focus of my paper is on the relationship between a father and daughter, and how that influences daughters’ selection of romantic partners in emerging adulthood. I wanted to look at research on the effects of the fathers’ own attachment, as well as maladaptive parenting behaviors/styles, and if this is connected and transferred to future partners. I looked at research on attachment styles of secure and insecure adult women during early childhood, adolescence, and emerging adulthood, as well as the relationship between the mother and daughter. It has been suggested that parenting styles, along with the parents’ own attachment preference can offer insight into the formation of daughters’ own attachment preferences. This attachment can be used to understand the model of transference of attachment to romantic partners. Earlier interactions provide a template for future interactions. This research sheds light on unhealthy family dynamics of individuals who did not have a high level of exploration within their family, and how that might contribute to maladaptive behaviors of identity and dependence within their romantic relationships.

Aproposed corporate bond issue is usually subjected to a credit risk assessement by credit rating agencies. The results of such an assessement provide a basis for potential investors to make decisions regarding the proposal.

Some investors consider duration to be useful factor when deciding whether to invest in corporate bonds. however ,other investors do not consider duration to be that useful and as such,they rely solely on the work work of credit rating agencies. Such investors consider the information provided by the credit rating agencies to be more useful than duration when choosing the bonds to invest in.

Required

Prepare a report that covers the following

a) A discussion of the factors that contribute to the credit risk and an explaination of the relationship between credit risk and interest rate risk

b) Identification and explanation of any two(2) approches that may be used to assess the degree of credit risk of a proposed bond issue

c) A critical discussion of the usefulness of duration as a measure of interest rate risk relating to the corpoate bonds

d) An evaluation whether there is a relationship between using duration and credit ratings when choosing bonds that an investor should invest in.

The following data set shows the number of chirps in one minute from a cricket and the temperature outside (in degrees Fahrenheit):

What is the rank correlation coefficient?  (Round to three decimal places.)

What is the critical rho value at a 0.01 significance?

Do we have correlation?

• No, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
• No, the rank correlation coefficient is larger (in absolute value) than the critical rho value.
• Yes, the rank correlation coefficient is smaller (in absolute value) than the critical rho value.
• Yes, the rank correlation coefficient is larger (in absolute value) than the critical rho value.

The table below gives the number of hours spent unsupervised each day as well as the overall grade averages for seven randomly selected middle school students. Using this data, consider the equation of the regression line, yˆ=b0+b1x for predicting the overall grade average for a middle school student based on the number of hours spent unsupervised each day. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.

Step 6 of 6 :  Find the value of the coefficient of determination. Round your answer to three decimal places.

Two Ways ANOVA

An engineer suspects that the surface finish of a metal part is influenced by the feed rate and the depth of cut. She selects three feed rates and four depths of cut. She then conducts a factorial experiment and obtains the following data: (Use Minitab)

1. Analyze the data and draw conclusions. Use a = 0.05.
2. Prepare appropriate residual plots and comment on the model’s adequacy.
3. Obtain point estimates of the mean surface finish at each feed rate.

Objectives

To become familiar with the uses of Radioisotopes through use of the Internet.

To be able to use your knowledge and understanding of radioisotopes to contribute to the discussion board.

Background

According to our textbook, “radioisotopes are powerful tools for studying processes in biochemistry, medicine, material science, environmental studies and many other scientific and industrial fields.”

Below is a list of radioisotopes and their half-lives. You will be choosing one of these radioisotopes to explore in more detail.

Assignment

Choose one of the radioisotopes from the list or find a radioisotope that is not on the list but interests you.

Using your book and Internet resources, find five interesting pieces of information on the radioisotope you selected. Suggested pieces of information may include:

How is the radioisotope formed in nature (type of decay)?

Risks associated with the radioisotope

Number of subatomic nucleons present

Stability of the radioisotope

How this radioisotope is used.

Is the radioisotope used as a medical tracer? If yes, for what body part or process? Briefly explain.

(These are just a few suggestions. See if you can find other interesting facts.)

Remember to site your sources in APA style.
