Encoding variability in software. At the 2012 Gulf Petrochemicals and Chemicals Association (GPCA) Forum, Oregon State University software engineers presented a paper on modeling and implementing variation in computer software. The researchers employed the compositional choice calculus (CCC) — a formal language for representing, generating, and organizing variation in tree-structured artifacts. The CCC language was compared to two other coding languages— the annotative choice calculus (ACC) and the computational feature algebra (CFA). Their research revealed the following: Any type of expression (e.g., plain expressions, dimension declarations, or lambda abstractions) found in either ACC or CFA can be found in CCC; plain expressions exist in both ACC and CFA; dimension declarations exist in ACC, but not CFA; lambda abstractions exist in CFA, but not ACC. Based on this information, draw a Venn diagram that illustrates the relationships among the three languages. (Hint: An expression represents a sample point in the Venn diagram.)

Each distribution center carries all products sold. Floyd’s customers are auto repair shops and larger auto parts retail stores. You are asked to perform an analysis of the customer assignments to determine which of Floyd’s customers should be assigned to each distribution center. The rule for assigning customers to distribution centers is simple: A customer should be assigned to the closest center. The worksheet Floyds in the provided datafile contains the distance from each of Floyd’s 1,029 customers to each of the five distribution centers. Your task is to build a list that tells which distribution center should serve each customer. The following functions will be helpful: =MIN(array) The MIN function returns the smallest value in a set of numbers.

- Answerrrr correctly for upvotearrow_forwardPsychopaths display a constellation of traits that render them a dangerous group of individuals. While psychopaths live among us, many can be found within the criminal justice system. In fact, many have a history of violent behavior in general, and sexual aggression in particular. Some research has suggested that psychopaths have difficulty distinguishing the emotions displayed in facial expressions and also attribute hostile intentions to innocuous situations. These patterns have been thought to contribute to the violence psychopaths display. In this study, the researcher presents a short video clip of a person describing a situation that is either innocuous or aggressive while displaying either a fearful or angry facial expression. Twenty psychopaths (n=20) are recruited to participate and are asked to identify their response by selecting it on the computer screen. Their response time (in seconds) is being measured in order to determine if psychopaths respond differently depending on…arrow_forwardAt a stop sign, some drivers come to a full stop, some come to a rolling stop (not a full stop, but slow down), and some do not stop at all. Test if there is an association between gender and type of stop (full, rolling, or no stop).

Do the data provide enough evidence to show that there is an association between gender and type of stop (full, rolling, or no stop)?

- In 2018, a consumer goods giant had more than 20 brands with more than $1 billion in annual sales. How does the company create so many successful consumer products? They effectively invests in research and development to understand what consumers want. One method used to determine consumer preferences is called conjoint analysis. Conjoint analysis allows a company to ascertain the utility that a respondent in the conjoint study places on a design of a given product. The higher the utility, the more valuable a respondent finds the design. Suppose we have conducted a conjoint study and have the following estimated utilities (higher is preferred) for each of three different designs for a new whitening toothpaste.
