# Easy Discussion

I’m working on a Business exercise and need support.

 Relationship of Height and Weight Each week, you will be asked to respond to the prompt or prompts in the discussion forum. Your initial post should be 75-150 words in length, and is due on Sunday. By Tuesday, you should respond to two additional posts from your peers. What does it mean when we say that there is a relationship between two variables? What kinds of relationships can there be between two variables. Give an example of two variables that are related. For example, my daughter has an hourly salary. Her paycheck amount is related to how many hours she worked. Give an example of two variables that are NOT related. Using the given Height and Weight data set, follow the steps in the weekly video or on pages 584-585 of the textbook for performing a regression analysis using Excel to analyze the Height and Weight Data set (assume height is the input variable x and weight is the output variable y). Once you have performed the analysis in Excel, state the correct simple linear regression equation and use the regression equation to predict the weight (in pounds) of a person who is 65 inches tall and the weight (in pounds) of a person who is 100 inches tall. Why might the regression equation you have found NOT be a good predication of the weight of someone who is 100 inches tall? How does this lesson apply to the workplace?

Steven,

Correct. Yes, based on the chapter we learned how regression analysis can be used to determine how a dependent variable (y) is related to an independent variable (x). In simple linear regression, the regression model is y = β0 + β1x + ϵ, which related to the simple linear regression equation and sample data along with the least squares method is used to develop the estimated simple linear regression equation y ̂ = b0 + b1x, where b0 and b1 are sample statistics used to estimate the population parameters β0 and β1.

In this discussion example, the intercept is -207.7 and the height is 5.25 so the formula

Weight= -207.7 + 5.25 Height

Week 7 Discussion- Relationship of Height and Weight

COLLAPSE

When we say that there is a relationship between two variables then it’s mean that when one is changing (increasing or decreasing), then another variable is also changing by the change of the first variable.

The relationship might be positive or negative. In positive relationships, if one variable is increasing, then other is also increasing and vice versa.

We have the equation

y=5.2536x-207.75

R^2=0.5129

Y= 5.2536x -207.75

Y= 5.2536(65)-207.75

Y = 133.734

Y= 5.2536(100) – 207.75

Y= 317.61

Since the information of the stature of the individuals is somewhere in the range of 60 and 80 so 100 inches is not in the regression. Yet, as we probably are aware of R^2=0.5129*100 = 51.29% which implies the percent of variety of y that clarifies for the lineal model. We can discover that it isn’t very exact, we generally will encounter an error.

Sounds good. The simple linear regression formula for the Height/weight data is y= 5.2536(x) – 207.75. To compute the estimated weight for a person who is 65 inches tall and a person who is 100 inches tall, you should substitute these values for x. The equations look like the following. Estimate weight for 65 inches = y(weight) = 5.2536 (65) – 207.75. The estimated weight is 133.7 lbs. Estimated weight for 100 inches = y(weight) = 5.2536 (100) – 207.75. The estimated weight is 317.7 lbs.

# easy discussion

I’m studying and need help with a Writing question to help me learn.

Read through a magazine, any magazine that you like to read. Look at the advertisements and find one that contains at least one logical fallacy. In your opening entry, complete the following:

1. Describe the advertisement precisely and clearly. Give the magazine title and publication date as well as the name of the product or service being advertised. Include a description of the images and any text in the ad. Be specific as you describe colors, images, product placement, font types used for text, etc.
2. Write out the argument implicit in the ad. Remember that an advertisement is an argument for a particular product or service. The ad designers are trying to convince you to buy the product or service. What are the claims being made in this argument? The thesis or final conclusion will be something like this: You should drink Coke. Once you have determined the thesis, look for the claims the ad makes to try to convince you to drink Coke. The claims are the reasons that support the thesis or conclusion. Write out the claims and the thesis for your chosen ad.
3. Identify any logical fallacies in the argument. Include any examples of egocentrism or sociocentrism. Explain and analyze those fallacies–how do they weaken the argument?
4. Explain how the advertisement could be modified to create a logically sound argument in support of the product or service.
