• Card 6 / 7: For the multivariate linear regression of the outcome of weight gain (lbs) on the exposure of cupcake consumption (continuous), we find a beta, or regression coefficient of 0.76, with a 95% confidence interval of (0.46, 1.06). Which one of the following is a true statement?
    A) For each 1?-unit increase in average cupcake consumption, we expect, on average, an increase in weight of between 0.46 and 1.06 lbs. The best estimate is 0.76 lbs.
    B) For each 1?-unit increase in average cupcake consumption, we expect an odds ratio of weight gain of between 0.46 and 1.06. The best estimate is 0.76.
    C) For each 1?-unit increase in weight gain, we expect, on average, an increase in cupcake consumption of between 0.46 and 1.06. The best estimate is 0.76 cupcakes.
    D) For each 1?-unit increase in weight gain, we expect an odds ratio of cupcake consumption of between 0.46 and 1.06. The best estimate is 0.76 cupcakes.
    E) The p?-value is above 0.05.

    Answer:
    A) For each 1?-unit increase in average cupcake consumption, we expect, on average, an increase in weight of between 0.46 and 1.06 lbs. The best estimate is 0.76 lbs.
