Suppose there exists a population where 60% of its members possess a certain characteristic. Let be the hat p proportion of a random sample of 399 members that also possess that certain characteristic. Determine the following probabilities. Round solutions to four decimal places, if necessary . Find the probability that the sample proportion is less than 0.56. P( hat p <0.56)=; = Box Find the probability that the sample proportion is between 0.64 and 0.67. P(0.64< hat p <0.67)=
