A professional golfer is shopping for a new brand of golf ball. He likes most of the features of one particular brand, but he wants to make sure that the brand has a desirable spin rate (the rate at which the ball spins on its axis after being struck by a golf club). To test the spin rate of this new brand of ball, the golfer hits the brand of ball on 100 five-iron shots, and a computer measures the spin rate for each shot. The computer then produces the following histogram summarizing the 100 spin rates:

Based on the histogram, find the proportion of spin rates in the sample that are less than 5500 revolutions per minute. Write your answer as a decimal,

Hi, I need help with essay on The position of infrared in the world of photography. Paper must be at least 2750 words. Please, no plagiarized work!

Therefore, it is the focus of this essay to answer what extent is infrared photography an artistic endeavor? Specifically, to investigate the extent that photography is a central aspect of the artistic message or a gimmick used to enhance the photograph without artistic merit. Infrared photography emerged in the early 1900s as the Royal Photographic Society published the first infrared photographs in October 1910. The development of infrared film was actually done by the US government during World War I to improve haze penetration in aerial and night photography. Scientifically, infrared films capture the part of the spectrum that is beyond our visibility, called infrared light. The diagram shows the electromagnetic spectrum, infrared has a higher wavelength than visible light. The Electromagnetic Spectrum. (n.d.). Retrieved from http:// The wavelength of infrared photography begins at 700 nanometers and ends at around 1000 nanometers, with visible light only between 390 to 740 nanometers of wavelength. This characteristic gives it the ability to capture images in the dark and create unique photographic effects and colors. Infrared photography really took off commercially in 1930, when the first infrared films were introduced and soon became very popular. Through time, infrared photograph established its irreplaceable place among the various styles of art photography and has continued its journey into the digital age. In investigating the research question, one of the greatest challenges is establishing a working definition of art. Philosophic investigations into the nature of art date to at least Greek antiquity, with Aristotle’s Poetics advancing the notion of mimesis as the central tenant of the art object. With social and technological progress came a change in the nature of artistic expression, such that during the Renaissance and Enlightenment periods the role of the artist changed from one of a craftsman to a Romantic notion of the artist as intellectual or genius. The 20th century experienced a shift from the Modernist to Post-Modernist era and witnessed revolutionary changes in the nature of art. Influenced by the scientific discoveries of Albert Einstein and Sigmund Freud, artists such as Pablo Picasso and Salvador Dali used art to explore these new intellectual paradigms of reality. Marcel Duchamp would even call into question the very nature of the art object. It is in this contemporary context that the notion of photography as art emerges. Perhaps the most seminal theorist in this regard was Susan Sontag, who in works such as Against Interpretation and On Photography formulated a number of aesthetic principles. Sontag argued that the nature of art is to capture that which is magical or irrational, and that art must be understood in terms of not only its meaning making content, but along with its formal elements as a comprehensive whole. While such a mode of understanding resists easy definition, for the context of this essay art is defined as the arrangement of formal style with content in a way to enact meaning through affecting the senses or emotions. Artistic photography affects the senses or emotions by selectively presenting aspects of our surroundings or objects in photographic form. Conversely, a gimmick is popularly understood as “a unique or quirky special feature that makes something “stand out” from its contemporaries.” 1 In the case of photography, gimmick is simply the employment of a feature or effect to enhance the picture. While gimmicks meet the formal criteria, they lack the necessary elements of intention and meaning to be considered

Unit IV Assignment

Course Project Part 1: Ergonomics Hazard Assessment

In Units IV, VII, and VIII, you will be building a course project that will assess ergonomic risks and provide strategies to

improve a workstation of your choice. Your final project will be a PowerPoint presentation due in Unit VIII. During Unit IV, you

will focus on the ergonomics-related hazard assessment.

Select a workstation that you are familiar with (preferably one that you work with regularly or have worked with previously).

Perform an ergonomics hazard assessment on that workstation. What are the potential stressors of that workstation? What

are the potential ergonomic risks and hazards? What type of injury could they cause? Explain each hazard in detail.

Your ergonomics hazard assessment should be a minimum of two pages in length.

As part of your hazard assessment,

you will include a minimum of two outside sources to support your findings.

One source must be from the Occupational

Safety and Health Administration (OSHA) website, which can be accessed by clicking the following link:

https://

1a)(5 points) What is “multicollinearity” in the context of regression analysis and what often causes this phenomenon, not from a mathematical but data collection viewpoint?

1b) (5 points)Why is multicollinearity undesirable; how would you attempt to remove this phenomenon from your analysis?

2) (50 points total) Worksheet “Our Sales” in the Excel file “Our Sales Data.xls” provides information about Annual Sales ($1,000,000) generated by a number of employees who can be considered sales representatives. Also in this worksheet are a number of employee-specific attributes, employee Aptitude Score on a standardized test, employee Age and employee Credit Score. The Aptitude Test is mandatory for all employees. Martha, the manager of the sales representatives, seeks to learn more about the relationship between the various employee attributes and Annual Sales. She directs her assistant, Derrick, to perform a regression analysis to analyze this matter (it so happens that both Marthaand Derrickare alumni of the execMBAat Missouri, so they knew about the potential benefits of a regression analysis).

Prepare each variable for the regression analysis.

2a) (5 points) Use plots to verify the nature of the relationship between sales and each of the other variables. Describe the nature of these relationships verbally and indicate how you would remedy any issues in the data. Do NOT include the plots themselves in your answer.

2b) (5 points) Determine the final (best) regression model to predict Annual Sales based on the attributes included in the data set. Show your numerical regression output (no graphs or plots), and explicitly state the regression equation. What does this regression equation tell you?

2c) (5 points) Comment on the validity and predictive power of the model you estimated in part 2c (NO need to conduct a residual analysis – base your answer strictly on the standard numerical Excel regression output).

2d) (5 points) Upper management is debating whether or not to keep Age as an independent variable. Martha is asked for her opinion. What should she recommend and what does she base her recommendation on?

2e) (5 points) Answer the same question as in part 2e, but now for the Credit Score variable.
