In studies for a medication, 13 percent of patients gained weight as a side effect. Suppose 449 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that
(a) exactly 71 patients will gain weight as a side effect.
(b) 71 or fewer patients will gain weight as a side effect.
(c) 77 or more patients will gain weight as a side effect.
(d) between 71and 80, inclusive, will gain weight as a side effect.

In studies for a medication, 7 percent of patients gained
weight as a side effect. Suppose 403 patients are randomly
selected. Use the normal approximation to the binomial to
approximate the probability that (a) exactly 29 patients will gain
weight as a side effect. (b) no more than 29 patients will gain
weight as a side effect. (c) at least 37 patients will gain weight
as a side effect. What does this result suggest?

In studies for a medication, 42% percent of patients gained
weight as a side effect. Suppose 50 patients are randomly selected.
Can we use the normal approximation to the binomial to approximate
the probability that exactly 22 patients will gain weight as a side
effect.
If no, explain why.
If yes, what mean and standard deviation do we use and what
probability do we calculate? (dont actually calculate).
Answer yes or no and follow up as requested?

approximate the probability that
(a) exactly 60 patients will gain weight as a side effect.
(b) no more than 60 patients will gain weight as a side
effect.
(c) at least 74 patients will gain weight as a side effect. What
does this result suggest?

Side Effects for Migraine Medicine
In clinical trials and extended studies of a medication whose
purpose is to reduce the pain associated with migraine headaches,
2% of the patients in the study experienced weight gain as a side
effect. Suppose a random sample of 600 users of this medication is
obtained.
Explain why you can use normal approximation to binomial
distribution to approximate the probabilities below.
Approximate, up to 4 decimal digits, the probability that 20 or
fewer users will...
