Suppose that a new treatment is successful in curing a common alment 63% of the time. If the treatment is tried on a random sampleof 100 patients, approximate the probability that fewer than 61 will be cured. Use the normal approximation to the binomialwith acorrection for continuity.Round your answer to at least three decimal places. Do not round any intermediate steps.(If necessary, consult a list of formulas.)Check2022 McG

A newspaper article reported that people spend a mean of 7 hours per day watching TV, with a standard deviation of 1.7 hours. A psychologist would like to conduct interviews with the 15% of the population who spend the most time watching TV. She assumes that the daily time people spend watching TV is normally distributed. At least how many hours of daily TV watching are necessary for a person to be eligible for the interview? Carry your intermediate computations to at least four decimal places. Round your answer to one decimal place.
A gardener buys a package of seeds. Seventy-five percent of seeds of this type germinate. The gardener plants 90 seeds. Find the probability that 60 or fewer of the seeds germinate. Use the normal approximation to the binomial with a correction for continuity. Use Table A.2 (Normal Distribution Table) and keep four decimal places with your answer. Intermediate calculations should be carried to a minimum of four decimal places.
