A random-number generator yields a population of numbers in a uniform distribution between 0 and 1 with a mean of 0.5 and a standard deviation of 0.289. You wish to find the probability that the mean of a sample of 50 random numbers is greater than 0.55. The z-score = with a probability (area) = (4 decimal places) because the area is to the (right left) of the z-score. Blank # 1 Blank # 2 Blank # 3
