At Burnt Mesa Pueblo, archaeological studies have used the method of tree-ring dating in an effort to determine when prehistoric

people lived in the pueblo. Wood from several excavations gave a mean of (year) 1240 with a standard deviation of 26 years. The distribution of dates was more or less mound-shaped and symmetric about the mean. Use the empirical rule to estimate the following.
a. a range of years centered about the mean in which about 68% of the data (tree-ring dates) will be found between________ and_________ A.D.
b. a range of years centered about the mean in which about 95% of the data (tree-ring dates) will be found between________ and_________ A.D.
c. a range of years centered about the mean in which almost all the data (tree-ring dates) will be found between________ and________ A.D.

Answer:

a. 1214 and 1266 A.D.

b. 1188 and 1292 A.D.

c. 1162 and 1318 A.D.

Explanation:

According to the empirical rule, in a normally distributed data set, 68% of data falls within one standard deviation above or below the mean, 95% of data falls within two standard deviations of the mean and almost all of the data is within three standard deviations of the mean.

If the mean year is 1240 and the standard deviation is 26 years:

a. 68% of data:

1240 -26 \leq A \leq 1240+26\\1214 \leq A \leq 1266

b. 95% of data

1240 -(2*26) \leq B \leq 1240+(2*26)\\1188 \leq B \leq 1292

c. Almost all data

1240 -(3*26) \leq C \leq 1240+(3*26)\\1162 \leq C \leq 1318

DanielleElmas [232]

The correct answer to this open question is the following.

Give examples of operational conflicts that could occur in a cross-cultural context because of different attitudes towards:1) time, 2) individualism.

Well, let's start with time. In the United States, time is of the utmost importance. There we have the old saying: "Time is money."

In the workplace, everything is based on the smart and efficient use of time. No time must be wasted in the workplace.

Individual effort is important in the American culture, but the team effort, the concept of being a good team player is very important under the following premise: teams can accomplish more than individuals.

What most Americans desire is individual recognition through team effort.

That is why team sports are so good in the United States because they exemplify the way teams function and what they can accomplish. For instance, college and pro football, basketball, and baseball.

The region that has a different approach, is Latin America. This does not mean that is better than the other, just that there are major differences between the two.

The management of time is very different in Latin American countries. It is not as important as the US. People in Latin America approach the concept of time in a more relaxed way. In Latin America, there is a more relaxed approach to time. Nothing is urgent, Things take time. Things are made at a different pace compared to the US.

And regarding individualism, Latin American people tend to prefer to be more individualistic to do things trying to get some recognition, The team concept is not as developed as in the US.

Sheridan Company uses a periodic inventory system. For April, when the company sold 450 units, the following information is avai
il63 [147K]

Answer:

Closing inventory - $10,160

Costs of goods sold - $9,600

Explanation:

Under the LIFO Method, the cost of good sold equals to

= April 23 units × cost per unit + Remaining units × cost per unit

= 300 units × $22 + 150 units × $20

= $6,600 + $3,000

= $9,600

Since the firm has sold 450 units, so out of which 300 units sold at a price of $22 and the remaining 150 units sold at a price of $20

The ending inventory equals to

= Remaining units × cost per unit + April 1 × cost per unit

= 270 units × $20 + 280 units × $17

= $5,400 + $4,760

= $10,160

Since on April 23, the 420 units were purchase, out of which 150 units are transferred to the cost of good sold and the remaining units 270 units at $20 is transferred to the ending inventory

1. Famous celebrities and the super-wealthy oftentimes pay others to do many of their household tasks for them. For example, the
poizon [28]

Explanation:

1) Famous celebrities and the people with lots of money are often seen with workers round them for their household chores/tasks. Although they are paying money for the work they could have done by themselves but if we analyze closely, they are actually taking advantage of the opportunity cost. The time when they were suppose to do the household work, now they are performing other task in that time which will be giving them much greater economic benefit, taking advantage of the concept of opportunity cost. For example, Cristiano Ronaldo can focus on his workout and daily exercise instead of making daily meals for himself, so he should have hired someone to do the meal work for him while he perform his workout which will help him on the field and will earn him much money.

2) Yes, it is possible for 2 countries to benefit from trade as a whole because they can get into an agreement by allowing free trade between the countries, for example, both the countries could agree that all the trade which will be executed between them would be tax free and no duties will be paid on them. This way the trade numbers would increase and industrialization would take place to meet the export/import orders. On the contrary, trading individually can be not so beneficial because there will be no free trade agreements between individuals i.e. no free lunches, that is why it could cost individuals much more than they can make money out of it.

3) One of the main reasons to oppose policies that restrict trade among the nations is that GDP. GDP is a measure of growth in any country, therefore when there will be no trade among countries, it would result in less productions of goods and services which which lead to less industrialization, which then will result to low employment and more unemployment, ultimately resulting in very low growth for any country and since growth is the only way forward for any nation, economists oppose policies that restrict trade among countries/nations.

I hope this detailed answer of mine help the poster.

Thank You and Good Luck.

yKpoI14uk [10]

Answer:

The correct answer is Clickstream.

Explanation:

Clickstream, also known as Click Tracking, is the route that any user takes once they enter a web page. With it, you can know what pages you visit and in what order, as well as how you get to each of them. It is one of the points that are discussed in web analytics when studying the behavior of visitors who come to them.

It is one of the vital elements to carry out the analysis of clicks of any online site, since it collects all the interaction of the users and the sequence they define with it. In fact, both for publishers and for webmasters and even for members of marketing departments, it is a very revealing and interesting graphic data set in order to evaluate strategies .

Knowing that flow of clicks allows you to check what are the behavior patterns of visitors when browsing a page, verify if the routes and hierarchies are well established and even analyze if there is any usability problem in any section of a page.

One more component within the entire framework that is part of the analysis of a website, especially in terms of usability. The clickstream is a concept that should be familiar if you have a website or consider its launch due to its importance when analyzing its good performance in terms of performance and user experience.
