Medical research has shown that a certain type of chemotherapy is successful 70% of the time when used to treat skin cancer. Suppose five skin cancer patients are treated with this type of chemotherapy, and let x equal the number of successful cures out of the five. The probability distribution for the number x of successful cures out of five is given in the following table:
c. Graph p(x). Locate m and the interval μ ±2σ on the graph. Use either Chebyshev’s rule or the empirical rule to approximate the probability that x falls into this interval. Compare your result with the actual probability.
d. Would you expect to observe fewer than two successful cures out of five?
