We want to create a model that looks at the association between diabetes and development of cardiovascular disease (CVD). The binary response of having cardiovascular disease (CVD) or not is modeled using the binary predictor DIABETES (where category “diabetics” is compared to baseline category of “non-diabetics”). A simple logistic regression analysis was performed in R. The following output is given. The coefficient estimate of the variable DIABETES is given below. Explain in detail what t he coefficient estimate of the variable DIABETES means (interpretation) using the words such as odds and odds ratio.

A large, national grocery retailer tracks productivity and costs of its facilities closely. Data were obtained from a single distribution center for a one-year period. Each data point for each variable represents one week of activity. The variables included are the number of cases shipped (X1), the indirect costs of the total labor hours as a percentage (X2), a qualitative regressor called holiday that is coded 1 if the week has a holiday and 0 otherwise (X3), and the total labor hours (Y). Use the R output below to answer the following questions. Using the output provided below, at significance level of 0.01, which of the three independent variables is/are significant? List only the significant variable(s).
