For a binomial distribution with n =100, and p = 0.05, does the normal distribution provide a reasonable approximation? Use the rule of thumb for normal approximation to the binomial distribution.

Question 2

For a binomial distribution with n =10, and p = 0.2, does the normal distribution provide a reasonable approximation? Use the rule of thumb for normal approximation to the binomial distribution.

Answer to Question 1

Since np = 5 >= 5 and nq = 95 > 5, the normal approximation to the binomial distribution is appropriate in this case.

Answer to Question 2

Since np = 2 < 5 and nq = 8 > 5, the normal approximation to the binomial distribution is not appropriate in this case.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.

Intradermal injections are somewhat difficult to correctly administer because the skin layers are so thin that it is easy to accidentally punch through to the deeper subcutaneous layer.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

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.
