The lengths of the individual fish follow approximately a normal distribution with mean 54.0mm and standard deviation 4.5mm Suppose that a random sample of four fish is chosen from the population, Find: 1) The mean of the sampling distribution ? 2) The standard deviation of the sampling distribution? 3) The probability that all four fish are between 51 and 60 mm ? 4) The probability that the mean length of the four fish are between 51 and 60 mm
