Consider the binomial random variable x with n = 50 and p = 0.5 . Suppose we want to use a normal approximation to find the probability of at least 30 successes. A reasonable approximation would be obtained by computing:
 a. P(29.5 < x < 30.5).
  b. P(x < 30.5)
  c. P(x > 29.5)
  d. P(59.5 < x < 100.5)

Question 2

The normal distribution provides a reasonable approximation to a binomial probability distribution whenever the values of np and nq both equal or exceed 5 .
  Indicate whether the statement is true or false

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.

The use of salicylates dates back 2,500 years to Hippocrates’s recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.
