FINC 615 American Public University WK5 Confidence Intervals & Sample Size Paper

FINC 615 American Public University WK5 Confidence Intervals & Sample Size Paper

Question Description

I’m working on a Accounting question and need guidance to help me study.

Topic: Confidence intervals and sample size

Using the data set you collected in Week 1, excluding the super car outlier, you should have calculated the mean and standard deviation during Week 2 for price data. Along with finding a p and q from Week 3. Using this information, calculate two 95% confidence intervals. For the first interval you need to calculate a T-confidence interval for the sample population. You have the mean, standard deviation and the sample size, all you have left to find is the T-critical value and you can calculate the interval. For the second interval calculate a proportion confidence interval using the proportion of the number of cars that fall below the average. You have the p, q, and n, all that is left is calculating a Z-critical value,

Make sure you include these values in your post, so your fellow classmates can use them to calculate their own confidence intervals. Once you calculate the confidence intervals you will need to interpret your interval and explain what this means in words.

Do the confidence intervals surprise you, knowing what you have learned about confidence intervals, proportions and normal distribution? Please the Week 5 Confidence T-Interval Mean and Unknown SD PDF and the Week 5 Confidence Interval Proportions PDF at the bottom of the discussion forum. This will give you a step by step example on how to help you calculate this using Excel. These PDFs will also help you in Tests&Quizzes tab.

Instructions: Your initial post should be at least 150 words. You must also respond to at least 2 other students. Responses should be a minimum of 50 words and may include direct questions.

In your first peer posts, pick another confidence level, i.e. 90%, 99%, 97%, any other confidence level is fine. Have fun and be creative with it and calculate another T-confidence interval and interpret your results. Compare your results to that of the initial 95%, how much do they differ? How useful can this type of information be when you go to buy a new car, or even a house?

In your second peer posts, pick another confidence level, i.e. 90%, 99%, 97%, any other confidence level is fine. Have fun and be creative with it and calculate another proportion interval and interpret your results. Compare your results to that of the initial 95%, how much do they differ? How useful can this type of information be when you go to buy a new car, or even a house?

Make sure you include your data set in your initial post as well. In this discussion forum you should be calculating 4 total confidence intervals. Two T-confidence intervals and Two proportion confidence intervals. Two in your initial post and then one in each of your response posts.

Week 5: SRI Funds and Business Ethical Obligations

This week’s lesson discussed SRI funds, corporate social responsibility, and environmentalism. Consider and comment on the following questions:

1. Consider the list of industries in your lesson in which SRI funds will not invest. Are there any on the list with which you would take issue? If you had to make an argument for the ethical premise of one of these industries (i.e. to have one of them taken off the list), which one would you pick and what would your argument be?

2. Consider the principle of profit maximization and the notion that businesses shouldn’t be obligated to do anything but make money. Do you think businesses have an obligation to help support society and the natural environment? Considering how poor businesses are at self-regulation (evidence of this is everywhere), should the government step in and require businesses by law to behave in certain ways (e.g. environmental and societal welfare laws)? Why or why not?
