Information about the tails of the normal curve asserts that the probability is 0.05 that a standardized score z falls below 1.645, and 0.05 that z falls above +1.645. Tell whether each of the following probabilities about fitness (measured as distance run in 6 minutes) is more than 0.05 or less than 0.05:
a. The probability of a z-score for fitness being less than 1.9
b. The probability of a z-score for fitness being less than 1.4
c. The probability of a z-score for fitness being greater than +1.7
d. The probability of a z-score for fitness being greater than +1.6
