Suppose the sediment density (g/cm) of a randomly selected specimen from a certain region is normally distributed with mean 2.65 and standard deviation .85 (suggested in "modeling sediment and water column interactions for hydrophobic pollutants," water research, 1984: 1169–1174). 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 2.65 and 3.00? b. how large a sample size would be required to ensure that the first probability in part (a) is at least .99?
