Answer to Question 1

VERY LARGE SAMPLE SIZES ARE VERY SENSITIVE TO DETECTING RESULTS, EVEN THOSE THAT ARE NOT PRACTICALLY SIGNIFICANT, BUT THE PUBLIC OFTEN THINKS THAT BIGGER IS BETTER.

Answer to Question 2

YES; A STUDY WITH A LARGER SAMPLE SIZE IS MORE LIKELY TO DEEM THE RELATIVE RISK TO BE SIGNIFICANT THAN A SMALLER STUDY WOULD.

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.
