DaughtersHeight is a data set on the height of adult daughters and the heights of their mothers and fathers, all in inches. The data were extracted from the US Department of Health and Human Services, Third National Health and Nutrition Examination Survey (use R studio for graphing).

Analyze these data with child height as the dependent variable. What can you conclude? Can female daughter height be related to the height of the father and/or the mother? Conduct a separate analysis with Type I and Type III sum of squares to examine whether any major conclusions rest on correlated explanatory variables.

Is it possible to run Levene's test with multiple comparisons in minitab? I am trying to run equal variances, the levene's test, and minitab somehow doesn't like the data. I already made 3 columns in minitab sheet

prompt:

A Datamore Company designs applications software for a number of large firms. A study is conducted to assess the satisfaction of these firms with the supplied software. Datamore decides to determine if the type of industry [Human Resources, Information Technology, Financial, and Insurance] is relevant to satisfaction. Additionally, the company would like to assess the abilities of its sales force [Britknee Phanshear, Megan Hearts, & Jessika Wahlstrom]. They send questionnaires out a number of companies in each of the industries in they do business and ask them to evaluate the company and their contact. The satisfaction scores are found below

So I input the table above in minitab in 3 columns. but when I runt the equal variances test, it comes out an error. Could anyone tell me step by step on how to get the levene's test working?  

Synthetically produced ethanol is an important industrial commodity used for various purposes, including as a solvent (especially for substances intended for human contact or consumption); in coatings, inks, and personal care products; for sterilization; and as a fuel. Industrial ethanol is a petrochemical synthesized by the hydrolysis of ethylene:

C2H4 (g) + H2O (v) <=>C2H5OH (v)
Some of the product is converted to diethyl ether in the undesired side reaction:

2 C2H5OH (v)<=> (C2H5 )2O (v) + H2O (v)

The combined feed to the reactor contains 53.7 mole% C2H4, 36.7% H2O, and the balance nitrogen, and enters the reactor at 310oC. The reactor operates isothermally at 310oC. An ethylene conversion of 5% is achieved, and the yield of ethanol (moles ethanol produced/moles ethylene consumed) is 0.900. Hint: treat the reactor as an open system.

Data for Diethyl Ether:

ˆ
H of = -271.2 kJ/mol for the liquid

ˆ
Hv = 26.05 kJ/mol (assume independent of T )

Cp[kJ/(molC)] = 0.08945 + 40.33*10-5T(C) -2.244*10-7T2

(a) Calculate the reactor heating or cooling requirement in kJ/mol feed.
(b) Why would the reactor be designed to yield such a low conversion of ethylene? What processing

step (or steps) would probably follow the reactor in a commercial implementation of this process?

From Dunkin Donuts to Just Dunkin! The famous American Donut’s brand is rebranding and closing stores across the world including Oman as its outlets have shut down for good. The demand for donuts in America is decreasing as customers preferring more healthy food with less sugar and fat.

The company’s brand CEO Mr. David Hoffmann said, “the rebranding comes as an effort to reshape the company’s strategic goals and focusing on drinks more than donuts.” While analyzing the company’s different products, the managers noticed that 60% of its revenue is coming from drinks like coffee while demand for donuts is declining.

The company redesigned its brand, and its stores making them look simpler. The company is also introducing new coffee experiences like nitro, cold brew, black...etc. The company will also introduce digital menu and drive through to fit the customers on the go lifestyle. The company will also reduce its employees as the new digital menus will eliminate the need of human employees, reducing the company’s costs.

Questions:

1. On the product life cycle, where the donuts fall? What are the best strategies the company can use in this case? (250 words)

2. Explain, how the demographic environment is affecting the company? (250 words)

From Pyramid Schemes to Mutual Fun

This case outlines the organizational structure found at Rite-Solutions who builds advanced software for the military as well as consumer-gaming platforms for casinos. The owners wanted to scrap the pyramid and rethink the company as a community. The company has a stock-market type game called “Mutual Fun” with the aim of making people feel relevant to the success of the business. So far the game has generated more than 50 innovative product and process ideas.

Management Update: Rite-Solutions was a 2015 finalist for the 10^th annual Bersin by Deloitte WhatWorks Award program recognizing innovation and excellence in critical areas of human resources.

Case Question: Says Jim Lavoie: “Being acknowledged as part of an organization’s future is all it takes for an employee to grow deeper roots in it.” First of all, explain what Lavoie means. Then consider the following questions: Do you basically agree or disagree with Lavoie? Do you think that it’s important to “grow roots” in an organization that you work for? What might it take for you to feel that you’re “part of an organization’s future” – that it’s worth it to sink “deeper roots”? What other factors might be important to you in feeling that you’re something more than a mere cog in some organizational machine?

Since 2009, the national minimum wage has been $7.25 per hour for most occupations in the private sector. Many of those who support an increase in the minimum wage believe this is one way the government could possibly reduce poverty, while its opponents believe that it creates unemployment and hurts low-skilled workers. The following items address the idea of raising the minimum wage from the current federal minimum of $7.25 per hour.

1) Describe who the suppliers and demanders are in the labor market. Is a government-mandated minimum wage a price floor or ceiling? Discuss the effect of a minimum wage law from a supply and demand standpoint, making sure to address the concept of surplus or shortage.

2) Raising the minimum wage will also affect the labor costs of businesses. What is going to happen to the prices these businesses charge for their products? And who is going to be most affected by these price changes, those with low incomes or with high incomes?

3) Discuss any potential changes in the incentives for low-skilled workers - those who keep their jobs and their hours - to increase their human capital when the minimum wage increases. What about those who lose their jobs or never get hired? Discuss the incentives for employers to substitute capital inputs (technology and automation) for labor.

In addition, cite the text, e.g. (p. 3), in at least one of your posts, proofread your post carefully, and read all student posts.

1. Key issues in childhood?  

Chapter 3 covers human development from birth to old age, or "womb to tomb" as we sometimes say. Developmental psychologists study physical, cognitive, and social change over the lifespan. After reading the first half of Ch. 3 on childhood development, what strikes you as one of the most critical issues in childhood development, physically, socially, or cognitively? What surprised you or caught your attention in this material? How might you apply this information in your own life?

2. Piaget Summer Camp?

You have decided to open a summer camp for children based on the cognitive development ideas of Jean Piaget.  Come up with one camp activity for each of Piaget’s four stages:

- sensorimotor,

- pre-operational,

- concrete operational and

- formal operational (you can identify specific ages if you like).

Explain how your activities fit the tasks of that stage, using the text and additional sources as references if you like (if you do, cite them at the end).

Make these fun camp-like activities!
