The sales for Sunflowers Apparel, a chain of upscale clothing stores for women, have increased during the past 12 years as the chain has expanded the number of stores open. Until now, Sunflowers managers selected sites based on subjective factors, such as the availability of a good lease or the perception that a location seemed ideal for an apparel store. As the new director of planning, you need to develop a systematic approach that will lead to making better decisions during the site selection process. As a starting point, you believe that the size of the store significantly contributes to store sales, and you want to use this relationship in the decision-making process. To examine the relationship, a sample of 14 stores was selected. The results are recorded in the accompanying table: Store Size (thousands of sq. ft) Annual Sales (millions of $) 1 1.7 3.7 2 1.6 3.9 3 2.8 6.7 4 5.6 9.5 5 1.3 3.4 6 2.2 5.6 7 1.3 3.7…
11) Consider each of the following scenarios and state whether the variable in question is a confounder, or whether more information is needed to assess confounding. Choose from Yes / No / or Need more information, and provide a very brief explanation for your selection a) In a cohort study of liver cancer among males, incidence rates of liver cancer among men with unhealthy alcohol use are compared to incidence rates of liver cancer among non-drinkers. Is gender a confounder in this study? b) A case-control study of the risk of beer consumption and oral cancer among men (overall OR = 2.8). In this study, cigarette smoking is associated with beer consumption and is a risk factor for oral cancer among both beer drinkers (OR=3.6) and nondrinkers (OR=3.7). Is cigarette smoking a confounder in this study? c) In a study of the risk of pulmonary hypertension among women who take diet drugs to lose weight, the crude relative risk of pulmonary hypertension comparing diet drug users to…

Management of a major company has made the following assumptions regarding their consumer profile. Over 60% of all shoppers are women Less than 40% of our customer primarily make purchases through online resources The average age of the purchasers of product B is below 45 years. The average weekly purchase of the top selling product A exceeds $50. The company hired market researchers to determine the validity of their consumers' demographic assumptions. The researchers conducted survey and focus groups to evaluate the purchasing pattern of the company's current consumers. In a survey of 400 consumers, 252 respondents were women and 148yrespondents indicated they purchase the company's products online. The average age of the respondents was 44 years with standard deviation of 10 years. The average weekly purchase of top selling products A and B by the respondents were $52 with standard deviation of $10.5 and $60 with standard deviation of $22.0 respectively. Determine which of the…
