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 most 96 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 66% of the time. If the treatment is tried on a random sample of 80 patients, approximate the probability that fewer than 52 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 90 patients, approximate the probability that at least 55 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.

In $14-17$ , use the normal approximation to estimate each probability. Round your answers to three decimal places. . $P(\text { more than } 20 \text { successes }), p=\frac{1}{10}, n=200$
