N is the number of trials. In an effort to reduce the population of unwanted cats and dogs, a group of veterinarians set up a low-cost spay/neuter clinic. The parameters are: - x is the number of successes. Assuming that a product actually meets this requirement, find the probability that in a random sample of 150 such packages the proportion weighing less than 490 grams is at least 3%. This outcome is independent from flight. Which lies wholly within the interval, so it is safe to assume that is approximately normally distributed. The probability is: In which: Then: 0. Assuming this proportion to be accurate, find the probability that a random sample of 700 documents will contain at least 30 with some sort of error.
