    1. Consider the data shown in this table measured in a sample of n=25 undergraduates in an on-campus survey of health behaviors. Enter the data into an excel worksheet for analysis.

    2. Estimate the multiple linear regression equation relating number of cups of coffee per week, female gender, and number of hours of exercise per week to GPA (consider GPA the dependent or outcome variable).
    Please explain in detail or a summary (roughly 200 words), responding to the questions posed in the problem.
