The following regression belongs to the analysis of self-reported happiness levels of a number of adults on a scale of 0-100pts. The unit measure for the happiness level variable is points. The x variables are the age of the respondent, hours of work per day, minutes of meditation per day, whether the respondent is a gym-user or not, and whether the respondent recently experienced a major life event or not. The gym-user dummy variable is 1 if the respondent goes to the gym regularly. The major life event dummy variable is 1 if the respondent had a major life event recently. The only interaction variable is between minutes of mediation and gym-user. Which of the following is/are correct? A) Every additional minute of meditation increases the predicted happiness level by 0.28 points (at the baseline), all else equal. B) The additional effect of a minute of meditation on predicted happiness levels is 1.78 points for gym users, all else equal. C) Those who work report a predicted level of happiness that is 1.5 points less than those who do not work, all else equal. D) A and B E) A and C F) B and C G) A, B and C
