Suppose a new cancer treatment has a 20% chance of curing a patient.

  1. a) For 5 cancer patients, what is the probability that: i) none will be cured?
    ii) exactly 2 patients will be cured?
    iii) at least 2 patients will be cured?

  2. b) For 500 patients,
    i) how many would you expect to be cured by the treatment?
    ii) what is the probability that more than 75 of the patients are cured?

Suppose that a new treatment is successful in curing a common ailment 71% of the time. If the treatment is tried on a random sample of 140 patients, approximate the probability that at least 101 will be cured. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps.

Suppose that a new treatment is successful in curing a common ailment 60% of the time. If the treatment is tried on a random sample of 55 patients, approximate the probability that at most 31 will be cured. Use the normal approximation to the binomial with a correction for continuity. Round your answer to at least three decimal places. Do not round any intermediate steps. (If necessary, consult a list of formulas.)

Suppose you have a treatment for a rare disease. If you apply this treatment to a person, they have a 32% chance of recovery. Suppose you apply your treatment to twelve patients. Show all work using the formula, do not use software. Let X be the number of patients who recover. (SHOW YOUR WORK) (a) To ensure that this is a binomial random variable we must assume something about our trials/ patients. What do we have to assume about our...

(a) You are a physician meeting with a patient who has just been diagnosed with cancer. You know there are two mutually exclusive types of cancer that the patient could have: type A and type B. The probability that he or she has A is 1/3 and the probability that he or she has B is 2/3. Type A is deadly: four patients out of five diagnosed with type A cancer die (D) within one year. Type B is less...
