Answer to Question 1

x is not a binomial random variable because there are more than two categories of outcomes. As the exercise is stated, each different brand (or make) of automobile is an outcome; therefore there are many different possible outcomes on each trial.

Answer to Question 2

D

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
