A bag contains 2 red marbles, 3 blue marbles, and 7 green marbles. If a marble is randomly selected from the bag. what is the probability that it is blue? 1/7 1/4 1/9 1/3 Use the given Information to find the minimum sample size required to estimate an unknown population mean . How many weeks of data must be randomly sampled to estimate the mean weekly sales of a new line of athletic footwear? We want 95% confidence that the sample mean is within $200 of the population mean, and the population standard deviation is known to be $1400. 189 267 133 325
