Suppose that the pH of soil samples taken from a certain geographic region is normally distributed with a mean of 6.00 and a standard deviation of 0.10. Suppose the pH of a randomly selected soil sample from this region will be determined.
a. What is the probability that the resulting pH is between 5.90 and
b. What is the probability that the resulting pH exceeds 6.10?
c. What is the probability that the resulting pH is at most 5.95?
d. What value will be exceeded by only 5% of all such pH values?
