Forty employers in a variety of fields and cities were surveyed in 2004 on topics relating to company benefits, and the degree to which employees were supported in terms of flexible work hours and child care assistance. One question asked if the employer had any experience or knowledge about attention-deficit hyperactive disorder (ADHD). Responses of either yes (y) or no (n) are shown below.

(a) Set up a 95% confidence interval for the proportion of all employers who have experience or knowledge of ADHD. (Round your answers to two decimal places.)

(The Evolution of Visual Storytelling)

Think back to when Facebook was first launched in 2004. It was simply a directory of user names, interests, and contact information. Since then, social media platforms have taken significant steps toward a more visual experience. Examine the changes these social media platforms have taken to pave the way for visual content and storytelling.

During the 2004 Olympic Games, a shot putter threw a shot put with a speed of 12.1 m/s at an angle of 43.7° above the horizontal. She released the shot put from a height of 2.07 m above the ground.

a) How far did the shot put travel in the horizontal direction?

b) How long was it until the shot put hit the ground?

You want to develop a regression model about the 2004 presidential election. The objective is to explain percentage of votes received by the Democratic candidate in each state. The explanatory variables are:

(i) unemployment rate in each state,

(ii) gender dummy (female =1 and male = 0),

(iii) a dummy variable for Bill Clinton’s appearance in the state to campaign,

(iv) an interaction term between the gender dummy and the Clinton dummy.

You want to consider a variety of models. Model I contains the variables in (i) and (ii). Model II contains the variables in (i), (ii), and (iii). Model III contains the variables in (i), (ii), (iii) and (iv).

1. Write down each of the above three regression models. Be sure to define all notations.
2. Interpret all the coefficients in Model III.
3. Using Models II and III, indicate how you would test the following hypotheses. Be sure to write down the null hypothesis, restricted and unrestricted models, etc.
   1. Unemployment doesn’t matter.
   2. Clinton’s appearance had no effect.
   3. Clinton’s appearance had same effect for both males and females.

The global marketplace has witnessed an increased pressure from customers and competitors in manufacturing as well as service sector (Basu, 2001; George, 2002).Due to the rapidly changing global marketplace only those companies will be able to survive that will deliver products of good quality at cheaper rate and to achieve their goal companies try to improve performance by focusing on cost cutting, increasing productivity levels, quality and guaranteeing deliveries in order to satisfy customers (Raouf, 1994).

Increased global competition leads the industry to increasing efficiency by means of economies of scale and internal specialization so as to meet market conditions in terms of flexibility, delivery performance and quality (Yamashina, 1995). The changes in the present competitive business environment are characterized by profound competition on the supply side and keenindecisive in customer requirements on the demand side. These changes have left their distinctive marks on the different aspect of the manufacturing organizations (Gomes et al., 2006). With this increasing global economy, cost effective manufacturing has become a requirement to remain competitive.

To meet all the challenges organizations try to introduce different manufacturing and supply techniques. Management of organizations devotes its efforts to reduce the manufacturing costs and to improve the quality of product. To achieve this goal, different manufacturing and supplytechniques have been employed. The last quarter of the 20th century witnessed the adoption of world-class, lean and integrated manufacturing strategies that have drastically changed the way manufacturing firm’sleads to improvement of manufacturing performance (Fullerton and McWatters, 2002).
