Suppose the sediment density (g/cm) of a randomly selected specimen from a certain region is normally distributed with mean 2.7 and standard deviation 0.75. (a) If a random sample of 25 specimens is selected, what is the probability that the sample average sediment density is at most 3.00? Between 2.7 and 3.00?b) How large a sample size would be required to ensure thatthe first probability in part (a) is at least .99 ??
