When rolling a pair of fair dice, the probability of rolling a total point value of 7 is 0.17 . If you rolled a pair of dice 1,000 times and the point value of 7 appeared 723 times, what would you probably conclude?
 
  a. This is not so unlikely as to make you doubt the fairness of the dice.
  b. Although not impossible, this outcome is so unlikely that the fairness of these dice is questionable.
  c. Since the total point value of 7 has the highest probability of any event in the sampling distribution, this is an extremely likely outcome.
  d. It is impossible for this to happen if the dice are fair.

Question 2

We create the sampling distribution of means from
 
  a. a random sample of all possible means.
  b. the region of rejection.

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.
