Weighted Mean - New Diet Cola
The document describes a survey that was conducted on a new diet cola. The survey reported the percentage of people who liked the taste of the cola in three different areas and the number of people surveyed in each area. To calculate the weighted mean percentage who liked the taste, the document shows how to set up the calculation by identifying the variables and weights, calculating the weighted values for each area, summing the weighted values and weights, and dividing the sums to obtain the weighted mean of 22.9%.

This document provides a summary of key concepts from Chapter 9 of the textbook on group behavior:
- It defines different types of groups including formal, informal, task, command, and interest groups.
- It outlines the five stages of group development: forming, storming, norming, performing, and adjourning.
- It discusses important group properties including roles, norms, status, size, and cohesiveness. Norms are the standards of acceptable behavior shared by a group. Status refers to a member's rank or position within a group.
- It notes that groups between 4-7 members can be most effective by balancing productivity and participation. Social loafing and pressure for conformity also impact

This document contains multiple choice and true/false questions about work teams from a chapter on understanding work teams. It covers the following key points:
1. Work teams have become popular because they enable organizations to better utilize employee talents. Teams generally have a positive impact on employee motivation.
2. The main difference between work groups and teams is that teams engage in collaborative work that produces results exceeding individual inputs, while groups primarily share information.
3. Common types of teams discussed include problem-solving teams, self-managed teams, cross-functional teams, and virtual teams. Self-managed teams empower members to make work-related decisions and typically have 10-15 members.
4. Effective teams require skills

Anti-Anginal Response against Disease History
Treadmill stress tests were applied to patients with angina pectoris before and 4 weeks after once-daily dosing with an experimental anti-anginal medication. The main objective for carrying out this study is to check if the improvement in exercise duration is dependent on the patient’s disease history. This data file represents the disease duration time (in years) since initial diagnosis and percent-improvement in treadmill walking times.
QUESTIONS :
(a) Identify the response and the explanatory variables with proper reasoning
(b) Check graphically if the dependency between “improvement” and “disease duration time” can be considered to be linear.
(c) Now, use a formal test of hypothesis to check for the linear relationship in part (b) and draw appropriate conclusion
(d) How does the disease duration effect the percentage improvement in exercise duration
(e) What assumption did you make to carry out the testing in part (c). Is there any other assumptions required to formulate a linear model for “improvement” and “disease duration time”
(f) Check all the model assumptions made in part (d) graphically and comment on the violation or non violation of the model assumptions with proper reasoning
