Business and Management Question – what is an adequate and reliable sample size. Obviously, for some populations 30 is enough.
1.what is an adequate and reliable sample size. Obviously, for some populations 30 is enough. But what about if you are not sure? Also, if you total population is only let’s say 1500, you would use it. Right? Yes – no?
2.Reading a newspaper article, you learn that the national unemployment rate is 5.1%. The next month you read another article that states that a recent survey in your area, based on a random sample of the labor force, estimates that the local unemployment rate is 4.7% with a margin of error of .5%. Thus, you conclude that the unemployment rate in your area is somewhere between 4.2% and 5.2%.
So, what does this say about the local unemployment picture in your area versus the national unemployment situation? Since a major portion of the interval for the local unemployment rate is below 5.1%, is it reasonable to conclude that the local unemployment rate is below the national unemployment rate? Not really. When looking at the confidence interval, you have some degree of confidence, usually between 90% and 99%. If we use z=1.96 to calculate the margin of error, which is the z value for a 95% confidence level, we can state that we are 95% confident that the local unemployment rate falls in the interval we obtain by using the margin of error. However, since 5.1% is in the interval for the local unemployment rate, the one thing that you can say is that it appears reasonable to conclude that the local and national unemployment rates are not different. However, if the national rate was 5.3%, then a conclusion that the two rates differ is reasonable because we are confident that the local unemployment rate falls between 4.2% and 5.2%.
When making conclusions based on the types of confidence intervals you have learned and will learn in this course, you will only be able to conclude that either there is a difference or there is not a difference. However, the methods you will learn in Chapter 9 will also allow you to determine the validity of a conclusion that states that the local rate is lower (or higher) than the national rate.
3.What to do , and how to look at the null hypothesis
4.Try finding a confidence interval yourself. A commonly used degree of confidence is 95%, corresponding to an interval extending about 2 standard deviations either side of the mean as the 68-95-99.7 rule says. In this case, the low-bound is about 15.7% and the high-bound is about 20.9%, thus a confidence interval for the proportion of times the dissolved oxygen levels failed to meet minimum standards says that although we can never know the true proportion, we can be 95% confident that it is no less than 15.7%, nor more than 20.9% of the time.
5.Watch the “p-value Approach” video in Ch. 9.
Consider the following as you watch:
Set up and design a scenario in which a hypothesis test is warranted. Identify all main terms above in this context.
Discuss your perceptions in class/online forum.
Discuss your perceptions in class/online forum.
6. Carefully define the following terms: Null hypothesis, alternative hypothesis, Type I error, Type II error, one-tailed test, two-tailed test

Business and Management Question – compare the US, Florida and European Constitution
This week’s discussion board is designed to have you consider how rights vary across “time and space”. In other words which rights are chosen to be included in constitutions and how these rights are defined and interpreted vary across countries and across states in the United States at the same point in time (the space dimension) and vary at different points in time within the same country. As you compare the U.S Bill of Rights and the Florida Declaration of Rights, on the one hand, with the European Union Charter, look for example at how rights concerning religion are described. Likewise, can you detect any differences in provisions for capital punishment or gun rights. Can you locate the right to privacy in the U.S. Bill of Rights? Is it found in the Florida Constitution or in the EU Charter? When you examine the European Charter on Human Rights do see any rights listed there that aren’t in Bill of Rights in the U.S. Constitution? Hint: Notice that the EU Charter contains a number of social and economic rights. Why would such rights be found in the EU Charter but not in the U.S. Constitution’s Bill of Rights? Give examples of what you discover and think about why these differences may exist. Keep in mind that these versions of “rights” were written at different points in history (the time dimension again). For example, the U.S. Bill of Rights were written in 1789 and ratified in 1791. The EU Charter evolved late in the 20th century. Does this time line tell us anything about how to think about rights? Additional ideas to consider about this assignment are found in the course announcements.

ASSIGNMENT
The works we’ve read so far in Unit One have been both difficult to understand and hard to relate to. We don’t go on sea voyages anymore, or gather in mead-halls, or go on pilgrimages to Canterbury. But it would be a mistake to assume that you can’t relate to Old and Medieval English literature. All of these works also demonstrate universal themes and deal with emotions and experiences we recognize today: the loss of a home or a way of life, the need to stand up to evil, the need for community, and taking long, life-changing journeys.
Choose one of the prompts below and develop a two-page (400-500 word) response that retells, or updates, one of the classics we’ve read. This is an informal writing assignment, so feel free to get creative and have fun with this assignment, or to get personal and expressive. You are welcome to use first person (I and we) and to write this in any form you choose — poem, short short, letter to the editor, journal entry, blog post, newspaper article, or even a series of Facebook status or Twitter updates — as long as your writing meets the minimum word count.
PROMPT #1:
Have you ever lost something that was really important to you? How did you feel about it? Did other people understand what you were going through, or did you constantly have to explain yourself? Have you ever moved? Did you miss your old home? Write a lament for something that you have lost. It could be something serious, like the death of a loved one or a move that was hard to adjust to, or it could be something not-as-serious, like the loss of a favorite childhood toy.

PROMPT #2:
You are trying to open up a restaurant / coffee shop that will become a social gathering place for your friends and peers. You want this place to be really cool — but also a place where people can relax and get comfortable. What kind of establishment will you open? How will you get people in the doors? What will they do once they get there? How will you keep them there for long periods of time and keep them coming back? Write a description or story of your ideal social meeting place.

PROMPT #3:
Imagine that you are going on a college study trip, or pilgrimage, with a group of four strangers. Where would you go and why would you be going there? How would you want your life to change? Who would the strangers be and how would they talk, act, and dress? A nerd? A prep? A jock? The pretty girl? Write your own social satire of the members of your group. This might be an ideal prompt for a blog post or a series of Facebook / Twitter statuses.
