Many business activities generate data that can be thought of as random. An example described in the textbook is the servicing of cars at an oil change shop. Each car entering the shop can be considered an experiment with random outcomes. A variable of interest in this experiment could be the amount of time necessary to service the car. Service time will vary randomly with each car.
We can often capture the most relevant characteristics of a stochastic process with a simple probability distribution model. We can then analyze the model to make predictions and drive decisions. For instance, we could estimate the number of technicians the oil change shop needs to service demand on a Saturday afternoon. Discuss the following:
What is a random variable?
How would you differentiate a discrete from a continuous random variable?
A laptop manufacturing company has implemented a 2-step process to test the quality of each production batch. In the first step, a technician randomly selects 15 laptops from the batch and determines whether they meet specifications. The batch is considered acceptable provided no more than 1 laptop fails to meet specifications. Otherwise, the entire batch must be tested in the second step. Historical data shows that 95% of the laptops produced adhere to specifications. Discuss the following:
What are the 4 characteristics of a binomial experiment?
Can we use a binomial distribution to model this process?
What is the probability that the entire batch unnecessarily has to be tested if in fact 95% of its laptops conform to specifications? (Hint: Use Excel’s =BINOMDIST() function to find the probability.)
What is the probability that the batch is incorrectly accepted if only 75% of its laptops conform to specifications?

Terrence is considering next steps for a client, Angela, who has come for therapy at the family counseling center where he works. When Angela scheduled her appointment on the telephone, she had described her concerns with marital difficulties, insomnia, and depression. During her first session, however, Terrence noticed that Angela had a very nervous demeanor, picked at her skin constantly, and had a rasping cough. When Terrence asked Angela about her employment, she admitted that she had lost her job and that her husband was angry about it. She said she was afraid her husband was on the brink of becoming abusive.
Terrence is not sure what to do first. He suspects Angela might have a substance addiction, but clearly she has several interlocking problems, and many are urgent. Should Terrence administer a screening for addiction or a more general clinical assessment? If he does decide to administer an addictions assessment, which of the many that are available should he choose and why?
This week, you differentiate between the use of addictions assessment tools and clinical assessment tools and review several assessment tools in order to evaluate one of them.
Objectives

Application: Evaluating an Addictions Assessment Tool
Addictions professionals can choose from many types of tools. Addictions assessments are divided into screening and assessment tools. Addictions screening tools are meant to determine if an addiction might be a possibility; they are not intended to diagnose. Addictions professionals use them to gain a basic idea of an individual’s orientation to an addiction. Addictions assessment tools are typically geared toward detecting dependence on or addiction to a specific, identified substance or behavior. These tools are broader in scope and often take special training and considerable time to administer.
The difficulty often is not in finding a tool to use with a client, but rather in choosing the most effective and appropriate tool from a wide variety. Though choices of screening and assessment tools is often made by the organization in which an addictions professional works, many considerations including cost, time to administer, training, and accuracy enter into the selection of the right test for each individual with a potential substance or process addiction. Thus, it is important that addictions professionals be familiar with the tools available to them and understands the effectiveness of these tools in assessing what they are intended to assess.
In this Assignment, you select one assessment tool from several well-known addictions assessment tools and research and provide an evaluation of its purpose, administration, and efficacy.

The Addiction Severity Index (ASI)
The success of an addiction assessment process depends on the competency of the addiction professional and the choice of the assessment tool, among other factors. Owing to the availability of numerous addiction assessment tools, it is pertinent that an addiction professional to have appropriate knowledge regarding the tools (McLellan, Luborsky, O’Brien & Woody, 1980). Although the organizations often choose addiction assessment tools for specific disorders, having appropriate knowledge regarding the tools ensures that an effective assessment of a disorder is performed. The addiction severity index is a structured interview that is intended to assess several problem areas in substance abusing clients.
The main purpose of the Addiction Severity Index (ASI) is to assess substance abuse, for example alcohol abuse (McLellan, Luborsky, O’Brien & Woody, 1980). The tool provides an assessment of other number of assessment areas, such as employment status, family relationships, legal problems, and psychiatric status (Carey, Cocco, & Correia, 1997). According to (Deady, 2009), the use of Addiction Severity Index (ASI) has yielded mixed results from different populations. However, (Carey, Cocco, & Correia, 1997) and (Deady, 2009) asserts that the tool has been found to have good inter-rater, split half, internal consistency and test-retest reliability. Moreover, the Addiction Severity Index (ASI) has been found to have good construct, content and criterion validity. The tool has been shown to have a varying internal consistency scales such as 0.89 for medical problems and 0.65 for employment problems (Carey, Cocco, & Correia, 1997) and (Deady, 2009). The Addiction Severity Index (ASI) has been used in treatment planning and evaluation (Deady, 2009). The tool typically assesses normative data b………………………..
